Well it's that time of the week again it's time for Chit Chat across the pond and this is going to be one of the most unusual interview setups we've ever done. I am still at the CSUN Persons with Disabilities Expo and I'm joined by three co-hosts. There's no pond here except maybe glass of water and I'm going to introduce them one at a time. I have for the very first time gotten to meet Dr. Robert Carter of the Tech Doctor podcast. How are you doing Robert? I'm great Allison it's such a pleasure to finally get to meet you and Steve. Yeah this has been a long time coming. We've been friends for years and been on each other shows and finally getting to meet up is awesome. Yes and at a situation like this where we have so much going on to promote accessibility and to create an environment where disability really becomes much less of an issue and you've been such an advocate in this area that it's really great that you're here so thanks for coming down for the day. Well like I've always said this is one of my favorite shows you guys get the coolest toys. Well I've also got Allison and I lost your name again. Allison Hartley. I asked her four times before we started. I promised I'd forget. Allison Hartley is Robert's co-host on the Tech Doctor podcast right? Yes and I'm also a huge fan of your podcast and it's great to be here. Oh fantastic I didn't know you listened. How awesome is that? All right and a good friend for a long time I actually met back at the podcast Expo 126 years ago Shelly Brisbane. Hi Allison it's fabulous to be here. I like interactive chit-chats across the panel where we can actually look at one another. Yeah that is kind of a funny thing here. So let me explain the setup here so Allison and Robert are both completely blind and Shelly is low vision and what we wanted to talk about was the changes in iOS 7.1 and kind of what that has brought to these guys and what kind of advantages they've seen and actually Steve and I were gone during the upgrade and didn't have internet's well enough to download the upgrade so we don't know what it does for sighted people we're learning what it does for the blind and visually impaired first. So I want to start with Shelly because you're low vision the challenges you face are different what are the kinds of things that are happening in terms of say contrast buttons that sort of thing? Well as probably a lot of people who've used iOS 7 know a big issue for everyone was contrast and the ability to read text. Oh it drives me crazy I can't read anything on this thing. Absolutely and it was a problem for for me it was for everybody else it was just a matter of degree and so 7.0 had a couple of features that would help you there was dynamic type which allowed you to have have larger text there was increased contrast which was just a toggle what they've done an OS 7.1 is actually flesh out increased contrast so there are now three settings that let you customize the for the way you want to work. So so is that is it just high medium and low contrast? No there's one which reduces transparency so in screens where it has that sort of fuzzy that well I call it fuzzy but that the background where it's it's not an opaque background it will actually reduce that somewhat. Okay I personally find that really annoying so I can shut that off now. Yeah but it's a toggle see it's it's not perfect I think they're probably going to do more but at least there's a toggle it's a starting place for us there's also a darkened colors which again goes to making it a little bit easier to see lines and to see it not so much with text that has more to do with background and then finally there's reduced white point which pretty much does what it says so all those sort of blindingly white screens in iOS 7.1 are a little muted when you turn that setting on. So that that does that work system-wide on all apps or does the app developer have to recognize those toggles? No those are system-wide and that's a nice thing from a evangelizing to developers point of view you don't have to do anything it's just I think you're going to see most of the effects on the home screen and in Apple apps but if you're using sort of static standard backgrounds I should say you're going to notice it and I think that the issue for people is going to be finding out which combination of those settings works so you can turn them all on and you might not need all of them on so as a low vision person I spent my first few days with iOS 7.1 going off on on off on and had a lot of fun. I love it. I finally have some settings that I thought I kind of like a combination. Yeah you might want to memorize those. So one of the things that really bugs the daylights out of me in iOS is that they got rid of buttons so like the back button and the done button and all that that's all just text and I find it I find them hard to find because of that. My personal new favorite feature in iOS 7.1 is called button shapes and again it's a toggle and it does two things it highlights some buttons for example the back button which is now just an arrow in text and it creates a highlighted back a background that is highlighted behind the text it doesn't highlight the text itself but it creates a background it's like if you took a highlighter and put it on the background and the other thing it does is it underlines some text links so that if you have an alert with a cancel in an okay button for example those text buttons would be underlined for you and it's just great and I use it all the time. So this is kind of funny when Shelley showed us this by the way these settings under general accessibility and then in the button shapes as soon as she told us about it Steve Robert's wife Vicki and I who are all completely sighted immediately turned those button shapes on and went yay that's so much better let me let me ask Robert a quick question with the uh with the underlying text turning on does that change how it acts in voiceover it does not doesn't change anything in voiceover okay so that has no impact on you you can sit there flip those switches all day and you don't care correct okay great any other uh oh how about the bolding that was fun bold text uh that and that that's an interesting one that's been in 7.0 but what they've done is accentuate the effects of it so when you turn on the bold text toggle the first thing is it'll say we're going to restart your phone so you just wait a minute have a cup of coffee have a sip of coffee I should say it doesn't take that long uh but in addition to what the first thing that you'll notice is that it bolds the text underneath icons on your home screen the second thing you'll notice is that if you pull up the search keyboard or any keyboard it will make the keys stand out from the backgrounds more whether that's light or dark depends on the keyboard uh and then the other thing is in addition to text they've actually added some lines that are it's hard to say to point at them and say well this is actually a new line but there are lines around the borders of icons so they're just a little bit easier to see they pop out from the background a little bit more okay I noticed also like I brought up my email and the subject of every email was a dark very dark bold title now uh yeah I think yeah that must be part of bold text I can't quantify it one way or another but I think I think that's probably a function of that we've been playing with all these settings and like I say there's the different combinations I'm still kind of experimenting with but uh can you can you change the bolding like is it a low medium higher is it just bold or no bold it's just bold or no bold unfortunately but I mean it's not it's not terribly obtrusive I think for most people it'll probably be fine but my sort of overarching theory of low vision accessibility in iOS is that it continues to be a work in progress and I said that when 7.0 came out and when you did increase contrast and then you went to a screen with only one toggle on it I said they're going to put more stuff on that and I think they're still going to do that I think it's and people they take a lot of feedback and they get a lot of feedback certainly from people like me so I don't know whether they'll do say a high medium and low bold probably not I would think it would be more likely that they would do sliders in the contrast realm so that you could oh that'd be none up and down a little bit yeah so um one of the reasons I I think the low vision stuff is really interesting on into the blind stuff is basically as we age if we're lucky enough to age we pretty much all can expect to have lower and lower vision I mean it you don't hear about people going wow I can sure see better than I did 10 years ago uh and and uh if we live long enough we're probably going to be blind so I figure it's good for everybody to learn about this stuff but I want to switch gears a little bit and go to Allison who Allison is really really excited about some bugs that are gone what what's uh blowing your dress there were a couple of bugs that were introduced in iOS 7.0 that drove me absolutely nuts um when you would push the sleep wake button to lock the screen a voiceover as it should would announce screen locked and then every now and then randomly again you would hear screen locked screen locked and I wanted to throw my phone out the window like you got I got it I understand I understand the screen is locked but yeah they fixed that in 7.1 thank god and also another really obtrusive bug that was bugging me was um if you were typing in a text input field whether that would be an i message or closing a tweet and if you were using the on-screen keyboard and you just overshot just a tad and you went up into the content of whatever it is you were typing focus would randomly jump and so you think you were chugging along typing at the end of of your text and it would go just somewhere in the middle and that so it would allow you to keep typing except to change where it was typing it would change where and it would not alert you that it was doing so it would it was that's just mean it was terribly mean I uttered several profanities over that we call those non-girl scout safe words on my show so they fixed that yes yes they have so what is the warning now now it's still it still lets you know that you're in the like in the message area and it still reads out the text when you touch it but focus doesn't change that's the big um that's the big change oh okay so they didn't just warn you they fixed the bug so it doesn't lose focus yes mm-hmm okay very cool any more bugs that are exciting you um not me but Robert has one that he's quite passionate about all right let's uh let's flip over to Robert then what's this bug you're talking about well the bug that I'm talking about is one that sort of got a lot of attention when ios 7.1 was released and people that I heard on twitter kind of panicked a bit it's a bluetooth keyboard bug and they actually tried to fix a problem that was in ios 7.0 when you used a bluetooth keyboard with voiceover turned on you're supposed to be able to tap the control key anytime you want voiceover to shut up and they fixed that just that's the same way on a regular keyboard right yes i'm on a regular keyboard if you're on a mac for example but in ios it was broken in 7.0 it didn't actually shut up voiceover but they fixed that in 7.1 so now the control key does shut up voiceover but unfortunately they broke another piece of it which is that when you tap the control key by itself the bluetooth keyboard stops operating in your edit box so you won't you'll keep typing but you won't you won't have any text being entered are you notified that you're not typing yeah well you can quickly tell that nothing is happening the way it should be because it'll just start saying tab tab tab or some random uh things and it's so that sounds worse than it was before yes it's it's a it's a breakage but the good news is it's not as bad as people first thought people thought this was some random bug that you could not reproduce you couldn't figure out what was happening but what's actually happening is right now it's just the fact that you press control by itself to silence voiceover that causes the bug but if you go ahead then and press control and option together and release those two keys together or release option before you release the control key then the bug will go away and you can continue typing in your edit field so there's a a pretty easy work around to it and they'll eventually fix it they didn't mean for it to happen this way it seems sort of like if you if i was fixing bug a i would have noticed bug b wouldn't you think well a lot of people are critical that that that it wasn't noticed or that it wasn't fixed and you know to be honest i mean i'm not thrilled that it's there but when i really think about it allison i've been using voiceover on ios devices since the iphone 3 gs and every single new version of the operating system has added more and more capabilities for voiceover so you know if apples like any other place are going to make a mistake now and then and i i don't want to be too hard on about that you know they'll fix it and it's i don't want to focus on the just the bug because a lot of progress was made in 7.1 i'm glad you brought that up i'm curious what you think about there was there was some investors thing maybe it was a conference call i forget where a guy was asking tim cook to justify with an roi why they're doing all these green initiatives and his answer was i don't do no stinking roi on that and by the way i don't do it when i make things accessible to the blind either did you guys love that loved it loved it loved it and it really is i think an honest statement about where tim cooks heart is as far as accessibility and the culture of the whole company is driven by that right yes the culture is driven by that and i'm so glad he did it because people have so much wanted to start rumors that now that steve jobs has passed that apple is going to forget about accessibility and i don't even we don't really even know for sure that steve jobs was the one really driving that although he did speak about it occasionally had to keynotes and things but it could have stopped it but maybe it was driven more by somebody else maybe but but the point is it's very clear that tim cook not only is planning to continue it but is very committed to it yeah that is fantastic what about are there any enhancements in uh... 7.1 that excite you yes um that there are actually a few that that are exciting one thing that's really nice now is that a voiceover allows you to use multiple speed synthesizers and it has for a while you can switch for example from american english to austrian english but now for the first time in 7.1 you can have independent speed settings for each of those voices so if you can understand american english at a more rapid speed that's great but you can slow it have it automatically slow down a bit when you switch to australian english what an interesting that there's something i would have never thought of that's fascinating yeah and i think it's it's going to be really useful for people who you know you make it you may decide you're tired of reading in one one version of english or maybe you even want to switch to french or spanish or different language to read something and it's nice to have that those voices a bit more customizable in that way well that's interesting no forgive me for my ignorance here but um do you buy separate voices for ios or you just use what comes with it those voices that that are that come with voiceover and ios are built in oh okay and uh how many voices are built in now i don't know how many are built in you know allison many i i know that there are at least six or seven english voices alone oh wow other languages as well okay okay anything else uh really blowing your dress up there robert well i can't say that i actually wear a dress too often alison but too often but okay i don't can't say that i wear one at all okay no rumors let's clarify these rumors here before they even get started all the esteemed professor professor says what well i i'm i'm i've worn a kilt so i may try to dress something there you go there you go but he's open minded yes i'm being trying to be very open minded about this but really i think what has happened is that that ios 7.1 just continues that iterative process of making voiceover work more smoothly and making it work well with the apps that come on the phone and of course we're always excited when developers do a little bit extra to make their apps completely voiceover friendly and so nothing in particular jumps out at me but i'm just thrilled with the way this process is is evolving continuing to polish the diamond then absolutely moving ever forward yeah there you go well um i'm people who have listened to the show for a long time know that i took a big risk and uh was it a year ago or two years ago steve i uh i did a uh a session at mac world called blindfolded where i worry uh i wear a blindfold and i use the iphone and the mac blindfolded um i was highly successful on the iphone and i crashed and burned in a in a deadly fire on the uh on the mac but you worked your way through it well technically i took the blindfold off is how i worked through it i got i got a document stuck to me like imagine something stuck to the bottom of your shoe and you keep walking around in a circle because you're stuck there i couldn't get this document off the bottom of my foot and i never i never did figure out what caused it i do know what caused it though is i changed something at the last minute right before i walked into the session would you never do right but anyway my point was that um even the two years ago i found a ios seven or i actually would have been ios six back then yeah maybe two years ago anyway it was i found it very easy to learn i found it it into it i mean i wasn't good at it but i understood it i knew what all the pieces were i even i finally even figure out what that silly rotor thing was for right right yeah that may have been ios five or six but you got on that pretty early on and my hats off to you for doing that blindfolded because it really made a great statement about how powerful accessibility is i think it did also help that i crashed and burned a lot of people in the session said that it also showed how hard it was that it wasn't just a drop in the you know easy peasy and so it is difficult to use but you can do it it's more difficult if you can't see the screen because of course this is a os 10 and ios what are they touch screens and icons they're totally designed to be visual well i actually told everybody that they would never make an accessible iphone that was just silly that couldn't be done so i'm a visionary anyway any other last minute things or should we start closing this out jelly got anything else well i i guess i would just echo some of what robert said about the iterative process that apple's going through and i think seven point one i call it the low vision upgrade it's the best upgrade that low vision users have ever had because it provides the most variety of features and as i said before i think what's exciting is that you have the ability to customize the low vision experience for whatever your needs are and everybody who's low vision has slightly different needs and i think that bodes well for all kinds of accessibility including something we didn't talk about it's not new in seven point oh one with the addition of switch control so that folks who can't use their hands to manipulate the the devices can use a head bounded switches or bluetooth switches that they communicate that they can tap in other ways and that's an interface that's just getting more and more robust with each iteration as well so i think there is an incredible amount of additional stuff accessibility can do and it's amazing that these pieces of glass and steel can be made as accessible as they are and that there's such a large ecosystem as you see when you go to the sessions at this conference where people are using ios in incredible numbers of different applications whether it's publishing or education and i you know i'm amazed that i live with this stuff every day so it's it's it's a pretty awesome time to be writing about and and living with the technology that actually works for folks who have different disabilities yeah i'm i'm glad you brought that up uh last week on the show the mac mommy was on talking with alistair jinx about uh teaching people to use ios in the mac and that sort of thing and and she teaches elderly people is kind of her specialty as she goes into people's homes and helps them set up their mac and their ios devices so i think she's probably going to be pretty excited to hear about the shelly just said can she come to my mom's house probably uh fly her out there but anyway that since she goes to their houses to know that this stuff is available and and a lot of us have aging parents who maybe we can help them out with the the low vision things as well and get them more excited to say hey if i turn this switch is that better or worse if i turn this switch better or worse kind of like being at the eye doctor where they say is it better or worse all right well let's start closing this out shelly you have a book coming out tell us about it why yes alice and i certainly do uh i'm almost completed a book called ios access for all your comprehensive guide to accessibility on the ipad iphone and ipod touch and the title you would think that would say it all wouldn't you uh basically it's your how-to guide if you want to know everything to everything to do with how to use accessibility it's not so much it's not very abstract at all it's follow these steps and you'll learn how to use a bluetooth keyboard or a braille display with a voiceover or use vision tools and so i cover all of the different groups of accessibility features in terms of different disability types and then i have a couple of chapters about apps i go into depth as to how to use the accessibility features with apple apps and then also with third party apps and that's about to come out in three weeks or so here and you can find out more at iosaccessbook.com oh fantastic fantastic i will make sure i'll put a link in the show notes to that for people if i if i take a picture of this qr code on the back of your card and i put on my website would that work that probably would work sure all right we'll give a try and allison how can people find you well robert and i co-host the tech doctor podcast and the best way to find us is to head on over to dr-carder.com we talk not only about new innovations in technology but try to get an idea uh and get to know the people behind it a little better we're both in the helping profession in our day jobs so we like to say that we intersect uh the human aspect of technology in our podcast oh fantastic one of my one of my top shows robert we're going to close it out here well allison you know i am a bit biased here but i will have to say that i do study the technology pretty carefully at least the accessible technology and i am absolutely convinced that apple is well more than a country mile ahead of the other big companies in accessibility at this time and i would encourage anyone who who needs accessibility to take a careful look at what apple has to offer because it's a lot right now that's fantastic and how can people find you people can find me by sending an email to techdoctor at dr-carder.com all right thank you very much this was fantastic a great panel i tricked these people into it right i had them uh stuck here during lunch so i tricked them into it i appreciate you guys all for coming thank you


A two-stage compression refrigeration system operates with R134A between pressure limits of 1.4 and 0.1 MPa. The refrigerant leaves the condenser as a saturated liquid and is throttled to a flash chamber operating at 0.4 MPa. The refrigerant leaving the low-pressure compressor at 0.4 MPa is also routed to the flash chamber. The vapor in the flash chamber is then compressed to the condenser pressure by the high-pressure compressor and the liquid is throttled to the evaporator pressure. Refrigerant flows through the condenser at a rate of 0.25 kg per second. Assuming the refrigerant leaves the evaporator as saturated vapor and both compressors are isentropic, determine the compressor power, the rate of heat removed from the refrigerated space, the fraction of the refrigerant that evaporates as it is throttled to the flash chamber, the coefficient of performance, and the theoretical maximum refrigeration coefficient of performance in these circumstances. There is a lot to unpack in this problem. We were given a low-pressure, a high-pressure, and an intermediate pressure. We were given a single mass flow rate. We were told that the exit of the condenser is a saturated liquid, so it's not supercooled or compressed. Similarly, the outlet of the evaporator is a saturated vapor and both compressors are isentropic. Because we have two-stage refrigeration here with a flash chamber operating as an intercooler, we're going to have the same cycle diagram as from our previous video. I will identify these nine state points for this problem and try to determine enthalpies. The reason I need enthalpies for all nine state points is because I want to calculate the work in, the Q in, the workout, and the Q out. From those, I can determine a network, a net heat transfer, a coefficient of performance, and then from those and the mass flow rates, we can figure out the power input, the rate of heat removed from the refrigerated space, and so on. So I want nine state point properties. Because we're looking up enthalpy for R134A, we're going to need two independent intensive properties to drive that lookup in the tables. The first independent intensive property I have for all nine state points is the pressure. I was given three pressures, 1.4, 0.4, and 0.1 megapascals. Those correspond to the high pressure, the intermediate pressure, and the low pressure. So the first thing I'm going to do is populate all nine pressures. 4 and 5 are the high pressure. 1 and 8 are the low pressure. And then 7, 3, 6, 9, and 2 are all at the intermediate pressure. I'll refer to that as medium pressure, just to make abbreviating it a little bit more convenient. With those pressures in place, I have nine of my required independent intensive properties. I need nine more. Two of those nine come from the fact that I was told the quality at the outlet of the evaporator and the outlet of the condenser. Two more come from the fact that the compressors are isentropic. That means S4 is equal to S9 and S2 is equal to S1. Two of them come from the fact that we are assuming the expansion valves are operating isenthetically, meaning H6 is equal to H5 and H8 is equal to H7. Two of them come from the mechanical nature of the flash chamber because it takes a mixed stream at state 6 and separates it by phase. 7 is going to be entirely saturated liquid and 3 is going to be entirely saturated vapor. That leaves me with one independent intensive property unaccounted for. That comes from an energy balance on the mixing chamber. At this point in the analysis, I will know H2, M.2, H3 and M.3, meaning I can calculate the enthalpy at state 9. So at state 1, I'm going to want to look up the enthalpy and the entropy because that defines state 2, and which I can look up the enthalpy. At state 3, I want the enthalpy at state 4. I will have the entropy from state 9 and I can look up the enthalpy. At state 5, I want to look up the enthalpy and I actually don't even really need to look up anything at state 6 because I already will have had H5. At state 7, I want to look up an enthalpy, which gives me H8. And enthalpy at state 9 will come from an energy balance. So I have 1, 2, 3, 4, 5, 6, 7, 7 lookups that I can do right now. Before that, I'm going to want to go into my R134A tables. In my tables, R134A is going to be tables A10 through A12. I have a pressure and quality at state 1, which means I'm going to want to go into my saturation tables by pressure, which means that I want table A11. Moseying on over to table A11, I need to find my pressure. My pressure at state 1 is the low pressure, which is 0.1 megapascals. 0.1 megapascals would be 1 bar. So at 1 bar, I can grab the specific enthalpy of a saturated vapor. And while I'm here, I can grab the specific entropy of a saturated vapor and write those down at state 1. That is 231.35 and 0.9395. From the entropy at state 1, I can look up the enthalpy at state 2. The first thing I have to do is fix the phase at state 2. I recognize that I have an isentropic compression process from a saturated vapor, which implies that I have a superheated vapor, but best practice is to check anyway. I'm going to find 0.4 megapascals, which would be 4 bar. And I'm going to compare my entropy to the saturated vapor entropy at 4 bar. So saturated liquid specific entropy at 4 bar and saturated vapor specific entropy at 4 bar are 0.2399 and 0.9145 respectively. The fact that my entropy at state 1 is higher than Sg at 4 bar implies that I have a superheated vapor. Now I can mosey on over to my superheated vapor tables and I look for a pressure subtable of 4 bar. At 4 bar, I see that I have entropies on either side of 0.9395, which I can use to interpolate for an enthalpy. For that, I need my calculator. So we're going to take 0.9395. Why did you not type 9? 0.9395 minus 0.9182 divided by, no, not divided by P. You can do a calculator. 0.9515 minus 0.9182. And then that is going to be equal to the thing that we're looking for, minus 253.35 divided by 262.96 minus 253.35, solving for x. We get 259.497. Let's make sure that makes sense. It does. So 259.497. At state 0.3, I have a quality of 1 again and the medium pressure, so I'm going to jump back into my saturation tables by pressure. And I'm looking for enthalpy. The enthalpy at 4 bar as a saturated vapor is 252.32. State 4, I have to skip for now. State 5, I have the quality of 0 and a pressure of the high pressure, which is 1.4 megapascals. So I find 1.4 megapascals, which would be 14 bar. And I see that the quality of 0 gives me an enthalpy of 125.26. So 125.26. Next up is state 0.6. At state 0.6, the enthalpy is the same as state 5, which is 125.26. Easy peasy. At state 7, I'm back to 0.4 megapascals, which is 4 bar and a quality of 0 this time. So my enthalpy will be 62 on the nose. 62. At state 0.8, I have the same enthalpy at state 0.7. So 62 on the nose. I can't determine 4 until I finish 9 and I can't do 9 until we figure out our mass flow rates and analyze the mixing chamber with an energy balance. So let's put the calculator away and step into an analysis on the mixing chamber. When I analyze the mixing chamber, I have two inlets, state 3 and state 2. One outlet, which is state 0.9. I'm assuming the mixing chamber operates adiabatically, that there are no meaningful changes in kinetic or potential energy, and I'm neglecting any work occurring in the process. So 1, 2, skip a few. We can jump all the way down to the sum in of m.h is equal to the sum out of m.h, which means m.2 h2 plus m.3 h3 is equal to m.9 h9. And then because I'm solving for h9, I'm going to be dividing everything by m.9. m.9 is the same as m.cycle. So I'm going to write this as m.2. I guess I could write m.9 still. Let's try to write that a little bit more neatly. m.2 over m.9 multiplied by h2 plus m.3 over m.9 times h3. I have h2. I have h3. m.2 over m.9 and m.3 over m.9 are going to come from the quality at state 6. Remember from the previous video, we had defined the proportions of mass flow rates within a flash chamber relative to the quality of the mixture's inlet. So at state 6, if we know the quality at state 6, that gives us the proportion of mass flow rate at 3 relative to 6. And then if we take 1 minus the quality at state 6, that gives us m.7 over m.6. So the quality at state 6 gives us m.3 over m.6. 1 minus x6 gives us m.7 over m.6. Looking at the mass flow rates, I see 2 is the same as 1, which is the same as 8, which is the same as 7. I see m.cycle is the same as m.9, which is the same as m.6. So instead of writing m.2 over m.9, I can write 1 minus x6. Then m.3 is the same as m.3. m.9 is the same as m.6, which is the same as m.cycle. So this can be written as the quality at state 6. And now I can determine h9 if I can look up 8x6. Fortunately for us, we have everything we need to determine a quality at state 6. So we go back into our property table lookups, and we figure out a quality at state 6. So I'm going to jump into my saturation tables at the medium pressure, which is 0.4 megapascals, which is 4 bar. And I'm going to be interpolating between the hf property, which is 62, and the hg property, which is 252.32. So quality at state 6 is going to be x6. Excuse me. I mean, it is going to be x6. h6 minus hf divided by hg minus hf. So the quality at state 0.6. Pop up our calculator, see if we can figure out which button is clear everything. Hey, look at that. Nope, much more better. And the quality at state 6, which was 125.26 minus 62 divided by 252.32 minus 62. And we get a quality of 0.3323. Let's call it 0.3324. OK, now up in our energy balance in the mixing chamber, we're going to take 1 minus that number. So 1 minus that number. Johnny got to use the correct minus sign. Multiply by h2. h2 was 259.497, 259.497. And then we are adding to that that same number again. Multiply by h3, which is 252.32. And we get 257.111. So I can write that up here for consistency. More importantly, I can write that down here. I guess this should be more accurately written as h9 is equal to 257.111, from which we can interpolate an S9. OK, now at state 0.9, we have an enthalpy and a pressure. That pressure is the medium pressure, which is 0.4 megapascals. I jump back into my saturation tables and I compare h9, which is 257.111, to 62 and 252.32. I observe that because h9 is between the two, I must have a saturated liquid vapor mixture again. Furthermore, I can interpolate directly for the entropy at state 9. The entropy at state 9 minus SF divided by SG minus SF is going to equal the enthalpy at state 9 minus 62 divided by 252.32 minus 62. So let's see if we can clear the calculator. Aha, and then we're solving. So this is going to be 257.111 minus 62 on the nose divided by 252.32 minus 62. And that's equal to the thing that we're looking for minus 0.2399 divided by 0.9145 minus 0.2399. Close parentheses looking for x. And we get 0.931484. Let's sanity check that before we move on. We have an enthalpy of 257.111. I see that that's what am I doing? That's not between SF and SG. That's bigger than SG. Therefore, we're going to be in the superheated vapor region. That makes sense. That's how we drew it on our TS diagram. What am I doing? Ah, I know what I'm doing. I'm demonstrating the way not to do it. Don't get too callous in your property table lookups. Remember to sanity check your numbers. Otherwise, we would have written down an incorrect entropy. And that would have been a mistake. Luckily for us, that was a learning opportunity, not a mistake. OK, now I'm going to look in my superheated vapor tables. I'm going to find 0.4 megapascals, which is 0. Excuse me, is a 4 bar. And I see that at 4 bar, I have enthalpies on either side of 257.111. Interestingly, they're the same two enthalpies as last interpolation. And our interpolation for the entropy is going to be between 0.9182 and 0.9515. So let's try that interpolation again. 257.111 minus 253.35 divided by 262.96 minus 253.35. And that's equal to the thing that we're looking for minus 0.9182 divided by 0.9515 minus 0.9182. Looking for x. And we get 0.931232. See, that's why we interpolated. We got a better number. It's better by 0.002-ish. Yeah. With 0.9312, I can perform the last interpolation for stay 4. I'll write that down. S9 is 0.0. 0.9312 kilojoules per kilogram Kelvin. Let's sanity check just to make sure that we didn't make any mistakes. 257.111 is between 253 and 262. And it is closer to 253.35. Therefore, our entropy should be closer to 0.918, which ours is, which is a good sign. Now, at stay 0.4, we have an entropy and a pressure from which we can determine an enthalpy. So the first thing we have to do is jump into our saturation tables by pressure again. We're going to find our high pressure, which is 1.4 megapascals, which is 14 bar. And we're going to compare our entropy of 0.9312 to the SF and SG at 14 bar. If my entropy was lower than SF, I know that I must have a compressed liquid. If it's greater than SG, that means I must have a superheated vapor. Mine is greater than SG, which means I have a superheated vapor. So we go back into our superheated vapor tables and we find 14 bar. And then we're going to be interpolating between an entropy of 0.9297 and 0.9658 for an enthalpy, which is going to be between 283.1 and 295.31, if we take 0.931232 minus 0.9297. And divide that by 0.9658 minus 0.9297. And we see that's equal to x minus 283.1 minus 295.31 minus 283.1. Wrap that in the correct argument and parentheses. 295.31 minus 293.1. Yes, yes. And then we're going to go back into our superheated parentheses, 295.31 minus 283.1. Yes, yes. Comma x, we get 283.618. So 283.618. And with that, we have all of the enthalpies at all nine state points, which means that we can proceed on to calculating our work in, our Q in, our workout and our Q out. For that, I'm going to need a little bit more space. So I'm going to shrink down my state point properties a little bit. Look at that, their travel size. First up, I have work in, which I recognize is going to occur in the compressors, since I'm writing this with respect to the mass flow rate of the cycle, I'm going to want to write specific work as power input divided by mass flow rate through the cycle. The total power input is going to be the power into the low pressure compressor, low pressure compressor, plus the power input to the high pressure compressor. Cannot believe that I said that accurately the first time. Power input to the low pressure compressor is going to be m dot one times h two minus h one. m dot one times h two minus h one. That comes from an energy balance on the low pressure compressor. I recognize that there's no opportunities for heat transfer because it's isentropic, which implies adiabatic. There are no meaningful changes in kinetic nor potential energy. I'm neglecting any work in the outward direction. I only have one inlet, I only have one outlet. It's steady state. Therefore, power input is going to be m dot one times h two minus h one, plus the power input to the high pressure compressor, which is going to be m dot nine times h four minus h nine. m dot nine times h four minus h nine. And we are dividing that by m dot cycle. So first proportion we have is m dot one over m dot cycle, is the same as m dot eight over m dot cycle, which is the same as m dot seven divided by m dot cycle, which is the same as m dot seven divided by m dot six, which is how we had defined one minus x six. So in my goal to write this in terms of as few dimensions as possible, I'm going to write that as one minus x six times h two minus h one. I'm running out of space. I'll move this a little bit more to the left. Hopefully I remember to speed up this part. If you still hear this, that means I forgot to speed up this part. Okay. Then we have m dot nine divided by m dot cycle, which is the same as m dot six divided by m dot six, which is just m dot one, excuse me, which is just one. So I'm going to add to this h four minus h nine. Cool. In terms of x six and enthalpies, one down, three more to go. For Q in, I recognize that the only opportunity for heat transfer to enter my control volume around the entire cycle is in the form of heat transfer into the evaporator. Therefore Q dot in is just going to be m dot eight times h one minus h eight. So Q dot in divided by m dot cycle, which is equal to m dot eight times h one minus h eight divided by m dot cycle. m dot eight divided by m dot cycle is the same as m dot seven divided by m dot cycle, which is the same as m dot seven divided by m dot six, which is one minus x six. So one minus x six times h eight minus h one. Two down, two more to go. Specific workout from this cycle is just going to be the power output of the cycle divided by m dot cycle. The power output of this cycle is zero because there's no opportunities for it. Zero divided by a number is zero. Three down, one more to go. Q out, there's only one opportunity for heat transfer to be rejected by my cycle when I draw a control volume around the entire cycle and that is in the condenser.  Again, that comes from an energy balance on the condenser.  Easy way to remember which way that is by the way is to consider the fact that the condenser is rejecting energy because it's rejecting energy. I should start with more energy than I finish. Therefore, a positive quantity would be beginning minus end, h four minus h five. Then I'm dividing that by m dot cycle. m dot four divided by m dot cycle is the same as m dot cycle divided by m dot cycle, which is just one. So this is h four minus h five. So we have one minus x six times h two minus h one plus h four minus h nine for work in. We have one minus x six times the quantity h eight minus h one for Q in, we've worked out of zero and Q out is just h four minus h five. So I'll clear up a little bit more space and we can get down to calculating numbers. First up for work in one minus x six. So we have one minus that was 0.3324 times the quantity, times the quantity, not h. What are you doing calculator? Times the quantity h two minus h one, h two was 259.497 minus 231.35. We are adding to that, adding to that calculator. Quality of state six again. No, excuse me. It's just one, plus h four minus h nine, which is 283.618 minus 257.111. And we get 45.2979. So 45.2979 kilojoules per kilogram. And then Q in, just going to be one minus 0.3324 times the quantity h eight minus h one, h eight is 62 on the nose, h one, oops. H one is 231.35 negative 113.058. Why did I write that as h eight minus h one? Okay, to everyone who was screaming at their device that I wrote that backwards. Thank you. H one minus h eight, which is of course 231.35 minus 62. So for some reason I had reversed that when I wrote it over here for no reason other than lack of coffee, 113.058. Workout is zero, zero is zero. Hooray. And then Q out is four minus five, which would be 283.618. 283.618 minus h five, which was 125.26. I don't know why I'm adding parentheses, but never hurts to add parentheses I guess. 158.358. So with workout, work, excuse me, with work in Q in workout and Q out calculated, I can now calculate a network in and a net heat transfer out. Good practice to calculate both of those, even though we don't need both because they should end up being the same. And if they're not, that is a good indication that we did something wrong. But of course we would never do anything wrong. 45.2979. Remember you shouldn't assume you'll make zero mistakes. You should assume you'll make mistakes and build in mechanisms to catch them. Q out minus Q in 158.358 minus 113.058. So that number minus that number. 45.299. So they should be the same within a rounding error. They are the same. Let's assume that that happened as a result of rounding the enthalpies and the quality. I'm comfortable enough with those two numbers to move on. So we have A asked us for the power input. Power input would be the mass flow rate multiplied by the specific work in. Note that that's mass flow rate through the cycle. The mass flow rate through the cycle was given because we were given the refrigerant mass flow rate through the condenser. So the condenser is going to be the same mass flow rate as the cycle. Therefore the mass flow rate through the cycle is 0.25. So I'm taking 0.25 multiplied by 45.2979. 0.25 times 45.2979. And we get 11.32 kilowatts. Kilograms, cancels kilograms. We're left with kilowatts, 11.3245 kilowatts. Then we were asked to calculate the rate of heat removed from the refrigerated space. So removed from the refrigerated space means we're looking for Q dot in. Q dot in, again, would be the mass flow rate through the cycle times little Q in, which is going to be 0.25 kilograms per second, multiplied by 113.058 kilojoules per kilogram. And then we weren't asked for a specific unit, but when we're talking about cooling capacity, we could express it in kilowatts, or we could convert it to the imperial unit of cooling capacity, which you'll remember is tons. A ton of refrigeration is 211 kilojoules per minute. Now, I could express it in kilowatts, I could express it in tons. We weren't asked for a specific unit. So just for funsies, let's calculate it in tons of refrigeration. That'd be 211 kilojoules per minute. So one ton, 211 kilojoules per minute. I know that I always say best practice is to express answers in the same unit system as you were given. So really we should be expressing an answer in kilowatts as per that model, but we're just having a little bit of fun to explore that conversion a little further. So if we take 0.25 multiplied by 113.058 times 60 divided by 211, we'll get an answer in tons. Let's see if we can type that into the calculator. You can do a calculator times 113.058 times 60 divided by 211. We get 8.04. By the way, note that that's the mass flow rate of the cycle because that's how we defined little Q in. You could have also gotten there by recognizing m.8 times h1 minus h8 is the actual Q.in. So we could have calculated h1 minus h8 as the specific Q in per unit mass of mass flow rate through that device and then multiply by the mass flow rate through that device, but we can't mix and match. The way that we defined Q in from the perspective of the cycle itself is per unit mass of the mass flow rate through the cycle. Therefore, we multiplied by the mass flow rate through the cycle. Part C, the refraction, excuse me, the fraction of the refrigerant that evaporates as it is throttled through the flash chamber, that would be the proportion of m.6 that is leaving at state point three that's asking us for m.3 divided by m.6, which is how we had to find that proportion which is represented as the same quantity as the quality at state six. So what we're really asking is the quality at state six, which was 0.3324, yeah, 24. Part D, I believe, asks us for the coefficient of performance. So the first question we have to ask is, is this operating in a cooling mode or a heating mode? We can deduce that it's going to be a cooling mode because we were given descriptions of the refrigerated space. It implies to us that we are trying to refrigerate a space and as a result of that, we are considering the cooling, the desired effect of this device. That means we're going to be using COPR and not COPHP. COPR is the desired effect divided by what you have to put in to make that happen. So that'd be Q in divided by the network in. The network in for this cycle is going to be the same as work in because there is no workout. That means I have Q in divided by just regular old work in. Q in was 113.058 divided by work in which was 45.298, 113.058 divided by 45.298 divided by 45.298 is 2.4959. So our coefficient of performance is about two and a half. So just like in the previous example problem, we could pose the question, is that a good COP or not? And in order to answer that question, we have to consider how well is this operating within how well it can operate in theory if everything were perfect. So how well is it performing compared to what is theoretically possible if we have Carnot refrigeration? For that, we are considering the low side temperature and the high side temperature because those will dictate what is theoretically possible. For that, we are going to be assuming that the high side temperature is the same as our temperature at state point five. We couldn't use the temperature at state point four because as soon as the temperature of our refrigerant dropped, we wouldn't be rejecting heat transfer to the surroundings anymore. So what we're assuming is that T max is pretty close to T five. That's an assumption we're making because we have nothing better to operate on. For the minimum temperature, we're going to make a similar assumption because we have nothing else to work from or we're going to be assuming that our minimum temperature is T one or T eight. Because I was given one directly, I'm going to write it as in terms of a state one. So for T five and T one, I'm going to be looking up the saturation temperature corresponding to my high pressure and low pressure respectively. So back once again to our R134A tables. So in my saturation tables for R134A, I see that the maximum temperature, T five is going to be 52.43 and the minimum temperature is going to be negative 26.43. So for maximum coefficient performance conditions, we are going to be trying to write our COP in terms of just proportions of heat transfer. So that's going to be Q in divided by network in, which we can again write as Q in divided by Q out minus Q in because the net heat transfer in has to equal the net heat transfer out if we are operating steadily as a closed system. And then I can write this as one over one over Q in times the quantity Q out minus Q in. And then I can bring that inside of the parentheses and I get one over Q out over Q in minus one. Then we make the Carnot substitution that Q H over Q L is equal to T H over T L. I recognize that for a refrigeration cycle, Q out is going to be Q H because the heat transfer rejected from the cycle is going into the high side temperature. So Q out is Q H and Q in is Q L. Therefore, this would be one over T H over T L minus one, which is going to be one over 52.43 plus 273.15 divided by negative 26.43 plus 273.15. And then we are subtracting one in that denominator. So we have one divided by 32.43 plus 273.15 divided by negative 26.43 plus 273.15 minus one. We got a maximum COP of 3.13. That means our COP, which is less than our maximum COP is possible and actually performing pretty well given the circumstances.


Welcome to the Core Report. I'm Corporal Remington Hall. And I'm Corporal Kathy Nunez. New gender and neutral standards for 29 different military occupational specialties became effective September 30th. A lot of people online seem to think gender neutral is just another way of saying lowered standards. That's not the case at all. The new standards cover requirements and tasks Marines already had to meet, but now are being formally evaluated on. Colonel Douglas Mayer from the Marine Corps Training and Education Command elaborates. Clearly defined standards are like a clearly defined mission. Marines get the mission done, and so by better clearly defining and articulating what our standard requirements are, Marines are going to train to those requirements, they're going to be prepared for the requirements, and that's going to lead to better success on the battlefield for the Marine Corps. For more on these new standards, click the link in the video description. Tomorrow, Parris Island is celebrating its 100th year of making Marines. Parris Island is responsible for training 41% of male Marines and 100% of the female Marines who join the Corps. So it means they train 100% plus 41, so 141% with... Over the last two decades, about 19,000 new Marines have come from Parris Island every year. The Depot has been responsible for an astounding number of Marines in its history. During World War I, Parris Island trained 41,000 recruits. Which pales in comparison to the Korean War when they trained 138,000 recruits, World War II when they trained 205,000 recruits, and the Vietnam War when a quarter million recruits went through the Depot. Follow Parris Island on social media for more on the anniversary. As of the beginning of this month, General Neller is officially on Twitter. On Twitter. What? Yeah, Twitter. At Jen Robert Neller is officially on Twitter. Well, that too, but General Neller is traveling from base to base to speak to you, the Marines. This is what he said during his visit to OneMath. We have a conversation with you about what that means, this contract that we have with each other. What you should expect from me as a commandant or any of your leaders, what should you expect from us? And on the other side of that coin, what should we expect from you? The commandant is continuing his tour, but if you don't get the chance to see him, you can keep up with him on Twitter. In fact, One Lance Corporal in 29 Palms missed seeing the commandant in person, but reached out with a tweet. To my surprise, and the Lance Corporals, General Neller responded. For more information about the tour, use the link in the video description and make sure to follow at Jen Robert Neller on Twitter. Remember, you can catch up on everything else going on around the core by logging on to our official social media sites. Thanks for watching everyone, and we'll see you next payday.

Hi everyone, we're back. Basel Chapman, 186 points up on the Dow, 20 points in S&P. It's kind of stalling out here. We're going to see how I talk about the overview in a moment. Let's finish this. The dollar is down 98.54. I think it was that, the 27th is why everything he makes is 29. I think that was a little earlier. That was, oh that was a 29th. The dollar hits 98.54, just about a point and a half of the old tie of the recovery high, five-year recovery high, and low and beholds a five-year, I'm sorry, two, three, two and a half year. What we're looking at is that the dollar has gone to a peak D yet again. Remember the peak D was made back on the 1st of October, 1967 and then it comes back down to 97.11 on the 1st of September. Rallys up to another peak D at night, that's four peaks higher than the Chapman methodology. 98.54, that was on the 29th of November and now it's hit a low today of 97.43, it's trading in 97.66. It hit the 200-period moving average. Every time it's done that, it's rebounded above it. I don't know if this is the time it's going to be different, but the weekly chart says there's a dreaded age pattern forming, so let's see if it's able to break away into the 98.50s over the next two weeks or if we're going to break down and go to 97. But that monthly chart has made a peak D and it was a peak D way back in January of 2017 and 103.82 before it went to the low of February of 2018 at 88.25. So this is a very nice bounce, but it's taken quite a long time. I like a strong dollar. I want to see a strong dollar. So the most important thing right now is the EURUSD. That had a balance and now it's given back some of the balance of 1.107. It used to get to the 1.118s to say, I've had enough of sideways. I'm breaking out. I hasn't done that yet and I better hold 1.00. And the USDJPY, that is the Japanese yen currency, dollar currency, has had a big pullback. I have to call this, I can't call it a G and an H because you don't get that. So this is an A, B, C, O. I have to rename this. I don't usually do that and not in this kind of manner where I have to move the down arrow all the way back, go to an up arrow over here. This becomes an A and that matches the dollar because very often it's not in price, but kind of direction. The yen moves closer to the dollar than the inverse, the mirror image of the C and a D. So that's the yen and the euro and this has gone to a sell. I'm going to put it down arrow here even though it looks like it's trying to run it. And it's a leg D. Oh, this is the same thing. We can beat D way back in April. Pulls back, comes back, runs, goes to a leg D and there's a chance that this week it makes a peak D. We'll see about that. So that's that. I just wanted to quickly say crude oil. It's very interesting. This is a big move up in crude oil. It didn't, oh, is this the same thing? So crude oil is trading at 58.44. I'm not sure what turned it around. That was a really ugly session back in the 29th, up in the 58th, 30th area and then tumbles down to 58.02 and then it has a rebound and now it's a little bit higher than that bar. It's at 58.53.  Look at this weekly chart. This is range bound and I don't want to ignore it because when you get this kind of reflex action, you remember this kind of, it's like a spring loaded action and in fact, let me do this. This is the most important thing. This pattern that I'm looking at right here says a breakout above. Yeah, we go. Maybe it's the mouse. It's not just allowing me to freely click. There we go. You see this kind of oval pattern? What's important about it is that if there is a break in the continuous contract of crude oil above 58.74, the 22nd of November, it can go a little higher and then what would happen is like an oval pattern and it breaks above it and go to the 59 area, but then it's probably going to come back into the 5740s. That's going to be the clue because if it breaks down again, that's decisively looking like a rectangle formation, but if it suddenly breaks down, it's very negative and if it does break, it starts to go to 5960 to 60.22, something that range. No, I think that's a little too high. 59, right there. So 5925 to 5975. If it breaks and holds in that area, that's also improved the weekly chart to the point where I would have to say there's now a chance that the crude oil can break from this pattern and start to move quite a bit higher. I didn't think I'd say that, but that's what I'm looking at. Higher highs and higher lows on daily crude. Not quite, but it's kind of like that. I'd rather prefer to think that of it as an oval pattern within this big rectangle where it just keeps coming back in. Look at this. This rectangle formation, it's just been stuck between 58 and about 53. It can go a little lower, a little higher, but it keeps coming back into the range. So it's a pattern within a pattern within a pattern. Let's see what happens. Okay, it's crude oil, but we have to look at the TLT trading at peak D. 139, 54 down 167. Isn't this interesting? Look, we had this spectacular gap down. This is really a big one the other day because it was also a bit of a surprise. On the 29th of November, it's up in the 140 area. Boom. Monday, gaps down two points. Remember, it goes down to 137.95. I didn't reversal yesterday. Huge move up. One of the things I think I spoke about it, but it's something that I usually talk about. I usually talk about when the market becomes vulnerable and layman's terms vulnerable means when there's a lot of selling. They never say vulnerable because it's going higher. They say vulnerable because they're selling. Money tends to flow out of equities and into the so-called safety of bonds. I say so-called safety of bonds because one day it's not going to work out that way. In the meantime, that's what we were looking at. So most importantly, what we are considering here is that the pattern that I call the dreaded H pattern, the lowercase H from 148.90, a weekly chart peak E pulls back to 136.54, runnies back up to about 145, pulls back to a new low of 134.45. The week of the 8th of November announced balancing. So once again, it's trying to form these arch formations and arch formations have a particular modus operandi. If there's a push back into the 143.5, 144 area, that's going to be really positive that this particular time sort of stuck in the low range trying to balance. All right, spoke about TBT yesterday. You'll see the TBT had a sharp decline yesterday and now it's balancing a little bit stuck at 25, 25.56. Just stuck in a range for now between the 26s and the 24s. I'll be right back, guys, I'm behind the 72 Basel Chapman Tiger's Ignitions Hour. A bunch of questions came in. I'll get to them as soon as we return. Hey, was there anything else I wanted to look at? No, I can now do it for questions. I'll be right back. Since 1984, Basel Chapman has been using the Chapman Wave methodology to advise traders of his expert market opinion. Well, originally hand drawing charts from the late 1970s into the 1980s, Basel noticed that prices under most circumstances virtually always had a certain number of legs to the upside before declining sharply. Later, Basel found that computer software which included the standard market technical indicators enhanced the degree of accuracy in calling price turns as well as market trend calls. Thus was born the Chapman Wave sequence. Using the Chapman Wave methodology along with other indicators, Basel Chapman advises his subscribers of his expert market opinion each market day with his opening call newsletter.

So, question, if one feels China deal will happen, isn't this a great buy regardless of current technicals? So, Kevin, you know, that's a really good question. A question you've asked many times before and the markets kept going higher. I have to... How can I put this? All right, let me just do this for a second. I'd spoken about this quite some time ago. And what I'd say it is, I believe that the president has found an absolute... The president has a particular modus operandi and he tends to use whatever works and he uses it until it stops working. Number one. Number two is, other than the tariffs, I suspect that the market would have been pulling back a little bit more over the last few weeks. So, absolutely, this is a tool for him. And he's used it very well. He would like it. I'd said about a month ago, I said, this is the period coming up, the period of the next three months, this is in November, December, January, maybe February, would make the most sense on a political format regardless of who's president at this particular point in the market at all time highs. This is the period where you'd prefer to see the market pull back and then have a great April, May, June, July, especially in July and going to August. You want to go into the election year with a market in full ball bull mode. It makes it very difficult to lose. If that doesn't matter who it is, it just makes it remember with Obama, I expected, I was one of the few people to say the next president will be President Obama, but I suspect he might be a one-term president and that was because of the economy at the time. I thought it would be very difficult for him because he was kind of anti-capitalist. Meantime, it turns out he was one of the great bull markets of all time. He never spoke about it, yet was. And now Trump has considered himself to be Mr. Market. There'll be a penalty to be paid for that, I believe, a very, very strong penalty, but not yet. It's still too early in the game. So I suspect that it is just a tool and that he doesn't want to actually resolve the problem. He wants it hanging over and he wants more than 51% of the problem to still be a problem so that he can manage the problem. He doesn't want to resolve it, and eventually when everything's concluded, he just wants a 51% win because that's what he calls winning. So I just needed to say that. So I don't see anything that's changed. For instance, now I can go to what I wanted to show earlier. Now's an appropriate time to just read your note. Look. Look what happened when the green nine-period moving average crossed negative and turned pink under the black moving average, the 14-period moving average. That started off the whole process I discussed way back in April when we went short the day before, the high. And then I called it a bad news cloud cover when we went short right here in September at 27,398. We went short 27,391. Seven points off the all-time high. And then it took a whole bunch of time, 13 sessions before it crossed negative. Then I missed this one. I want to do, we just missed it, but we did go short about 120 points off the high back in. That was the high of September. Bad news cloud cover. The high was right there. I think it was the 16th of the 12th of July. And then it came down to 14 days before they crossed negative. Now I've drawn in the oval pattern, but I decided I'm going to go to the high of the 19th of November, our very first time to attempt to short on the 28,090. And then we took it out. We went just a little bit above it. We went to 21,000 all-time high, 28,174. So we were very fortunate. I think we were fortunate two days ago at the open, about 80 points off the 70 points off the high, we got short. And now I'm going back, just to be cautious, I'm going bad news cloud cover. I'm going all the way back to the 19th. I should start it over here. But the fact that yesterday we broke decisively underneath. Look, we broke decisively underneath. Every other time we took ages before we broke decisively underneath the 14 period moving average. That happened yesterday. So I can just go with it. What I see my chart says that yes, we could be very choppy, but choppy with lower highs and lower lows. And we might not go all that much further to the downside because once we crossed negative, it took just two more big down candles in the daily back in October to go the October first low. And then when it crossed very negative in, that was in July. And then it crossed negative the first of August. It took 1, 2, 3, 4, 5 and a big bounce, 6, 7, 8, 9, 10 and 11 sessions later, 22 sessions from the cell signal. Before you turn up and you start the big move up. So I suspect that we will go down and then the big test comes with a rally. Maybe sometime a third week of December. You remember my rule of thumb is that if the Dow survives, the usual September October down moves. And last week of October, first week of November, it's trading near the yearly high. There's a good chance you're going to close near the yearly high. So we'll see. So I'm just trying to do my analysis as best I can. The other thing to look at here is, that's to answer your question, I think you're right in your assumption. I think I'm right in my analysis. There might now be a compromise between the two because now we know that Trump is using it in shorter timeframes as a tool. And at a certain point, that gets worn out. People start not believing it anymore. So all I can say is yes, we've got, was it December the 15th? Deadline, the 12th and the 15th. So we've got the deadline coming up in just over a week. And let's just deal with it one at a time. So right now I think this is just a bounce. I've answered your question. I do think limited upside, but maybe it's limited downside. And the big thing about it, if I can show it, I just show my subscribers every day, is that I showed here the daily chart, the MACD is very negative, and even with those bounces, the cash is still only at 40, or is it 49%? And I think there's still room on the downside.  I think there will still be this Chapman Way 4 to the upside. I think there'll be a Chapman Way 5 under 27,000, 325, the 27,200s will be the key test. A break under that said, oh, now there's much deeper weakness. And if you look at, I don't want to take too much time. If you look at a lot of the key stocks, many of them needed a digestive phase, and that's what they're getting right now. Then now I can get to some of the questions in the den. The first question was, whoops, am I going to see the first question? Yes. Let's see. I apologize for being late for my midday update. I just had to do some, I thought I got rid of all the snow and the ice and everything, but some of it had just showed up on the stairs outside, and I just wanted to make sure that it was clear as I was busy working out there, and I forgot my type. So question, Basil, is continuing the saga of CLVS? What now looks like doji is forming half way marker or turn around Tuesday, also a 3.382 film level. So yesterday the questioner said, what about it? It was in the, right here, CLVS type 22. Again, by mistake. I'll be back. If you're in the CD market and looking for a secure investment, the Tiger First Mortgage Program may work for you. The security for these first mortgages are building lots in the tax opportunity zone in St. Petersburg, Florida. The tax act of 2018 set up tax free zones across the country where you can build and hold for 10 years and pay no tax on the profits, which makes these lots valuable. The investment is anywhere from $30,000 to $75,000. The interest paid is 7% yearly paid on a monthly basis. According to bankrate.com, the best rate for a four-year CD in the country as of February 20th is 3.1%. A $50,000 investment at a normal four-year CD rate of 3.1% would give you income of $1550 per year or $6,200 over the four-year period. That same $50,000 investment in the Tiger First Mortgage Program would give you $3,500 per year or $14,000 over the four years. What should you prefer? $6,200 or $14,000 of interest on your investment. If you would like more information about the Tiger First Mortgage Program, you can call me at<PHONE_NUMBER>.

TIGER TV, TASTFN.com Visit TIGER TV, TASTFN.com for the latest market information. Hello. So, CLVS, this is CLOBIS on Coalogy Inc. Biotech. We've had one of our TASTFN listeners have sent, periodically sends in really good calls on biotech stocks. And this was one of them and it screams from the 2.93 was the low in, that was October the 29th, and it screams all the way to the high of three days ago at 17.37. So let me type that in here so I know what it is, I don't have to keep checking, it's 17.37. And then what happens? It pulls back. So what happens is yesterday, it pulls back a little bit, it's in the 15s, 15.60 or something, and I get a question in the den, will I be able to buy Clovis at 12s? And my answer I typed in was, are you kidding, it's a biotech, of course you're able to get in the 12s. Well, during the day, I'm looking and suddenly I see Clovis is down one and a half, then it's down two and a half, then it's down three, and then it's down five. Well, it was a five, five percent, I don't remember. But it comes down to $11.57 down from where it was. So yeah, and now it's trading at 12.04 at 11.39. Now this is, 11.39 was low. So this is a biotech stock, it made a peaky with a doji, long-legged doji candle, you know my rule of thumb, if it takes out this kind of candle, if it takes out the wick halfway into the lower part of the long-legged wick and stays there for on a shorter time period for a little bit, be careful because it's going to test the low. Well, not only did that, it plunged. Now I'm going to say because of the single-legged A up, and it was obviously all news related, I don't know what the hell, maybe I can do that now. News in the series, my little icon in the trade station, how do you ever use this? News window, news window, Clovis, okay what does it say, it says Clovis Oncology Option Alert calls, the $15 calls, twice it says $25 calls, I don't know what it was, Clovis Oncology. Shares increased by 1% to 11.79, the market cap seems to be at the most recent rating now. I don't know what it was. Anyway, the fact is that's what it did and now you've got to be really careful. I'd say hold off a little bit, let's give me a yell if you see this thing trading in the, see the 40 period moving average at 10.47 cents that has been cut by a 70% going from 1737 to the 1038 level, I think that that's a possibility. I don't really want it now, I'd be wrong if it's 70 balances to 13.18, 14.10, then I'm going to say okay now it's got the rectangle formation, you can stay there for a while, you can trade it from the bottom to the top and get out bottom to the top and just keep getting out. I'm just going to say hold off and I wish there was something else that we could know about it, but all I can say is I'd be a little careful, yes it did hit the 12, but if you do remember I said let's see how it handles the 11, what was that number, 11, I think it was 11.57 area, so it's just taken that out, I'm going to say give it a little more time, put it on your list, but I don't think I'd be running to buy it now, the news is out and I'll start jesting those gains, okay next question I had was right here, where is it? Questions on the right here, answer is a weekly, oh the TLT, so the TLT, the questioner said got out of some lung positions yesterday, what now and worried about the weekly chart, lower case H that went quite sharply lower, but then since the week of, okay the lowest 136.54 the week of the 13th of September, it bounces all the way to the 145 area and makes an arch formation, it comes back, closes below that low, it goes to 134.45 the week of the 8th of November and since then it's closed above that left side low five times, well one, two, three, this is the fourth week but I don't know where it'll close, but this is the fourth week that it's much higher, so I am going to say that I think that there's another arch formation forming and the big question is when can we expect a leg D or could we expect or should we expect a leg D in the monthly chart and I'm going to say the next really big decline in the Dow, if it happens over the next six weeks I wouldn't be surprised if the TLT rally sharply and that the one yields come down maybe to the 135, 133 area in the TLT to retest that level and then there'll be a rally at some point going to a leg D above 148.90 and that's the way I'm looking at it purely on a technical basis, so I think there's going to be a chance to buy the TLT so does that say the TBT rally is often the questions yesterday in play, probably as a bounce it could be but I'd rather use these things as visual tools because trading it is ready because you've got the overnight trade, anything can happen overnight and it only trades during the day, it's like the GBTC, GBTC which is the Bitcoin ETF only trades overnight so anything can happen so I'm just going to say yeah let's just watch this and to be real clear if there is a move in the TLT below 137.95 that's the candle low of the second that suggests that yields are going to go quite a bit high in the shorter term and that the TBT will be in play and that it should challenge is at 25, 25 right now should probably get into the 26s. At this particular point it's real tough to play. All right does up 193 further buying coming in, okay question I had was right here if I can read it, XLI, XLI is in fact had a peak E this is not was this the 27th as well now I think it was the 26, yeah 26 the industrials made a high this is the XL, there we go XLI, there's the S&P select industrial spider fund trading at 80.52 was it 82.65, 2 points it's just not a big deal yesterday it did look like it was a big deal there's an island reversal here can't ignore island reversals does that get filled in I suspect it will get filled in but this is really this is a much better reflection of the industrials than the Dow 30, the Dow 30 is not really an industrial anymore it might by accident as some industrials so what's as closely tried to rally it went all the way to 80.90 yesterday's over 79.26 it's really important to follow it next question I think was a very good one GD wants to know about C a cloud CRM minus 5% oracle minus 3.3 workday minus 9 and now is down as well now is down 3% Microsoft is down 1.3% yeah hey good point I'll check that out as soon as we return so I'll drop in time conditions are does up 198 as it means up 21 and then I quickly talk about my stream of stock that I have subscribers this morning I'm certain you are or strive to be one of the best of the best at everything you do in life it's the most common trait that we tigers and tigers is share if you're looking to become the best of the best when it comes to managing your money let me teach you to do what most wealth managers tell you can't be done which is how to time the markets I'm Steve Rhodes author of mastering probability and for the last 12 months timer digest has been tracking my newsletter signals which have earned me the ranking as their number one market timer in the nation for the S&P 500 for the last 12 6 and 3 months timer digest also ranks me as the number one market timer for gold as well the fact is markets can be timed and I'll teach you the exact set of tools that I use it is transform me into one of the best at what I do sign up for mastering probability today by clicking on the newsletter tab on the homepage of tfnn.com get immediate access to workshops where I take you step by step how to use an extraordinary set of tools as well as provide great market calls to sign up today if you haven't checked out the newsletters page of tfnn.com what are you waiting for all of the tfnn newsletters are informative up-to-date affordable and must have for every trader looking to gain a competitive informational edge in today's markets tfnn newsletters cover every aspect of the markets to offer you the very latest in market news plus new subscribers get to test drive our newsletters risk-free for 30 days from all aspects of the markets including stocks bonds metals commodities and tech there's a newsletter to fit your needs exclusively from tfnn stay informed each day you trade and get the competitive edge that will help you stay ahead of the game visit our newsletters page by going to tfnn.com and click the newsletters button near the top of the page tfnn.com educating investors you know what's cool taking something that's good for you something specifically formulated to help with weight loss better sleep stress reduction and the need to detox nika our hunter and gatherer ancestors found all their nutritional requirements for health in their wild environment but today our food sources no longer contain the vitamins minerals and nutrients our bodies need to stay healthy and strong that's why we need primal edge daily nutrition it includes a special blend of ionic soil based vitamins minerals fatty and amino acids in an easy to use liquid form primal edge is powered by highly concentrated folic and humic acids nature's preferred delivery system they've been called miracle molecules because like sunlight air and water life cannot exist without them that's right page they ensure we receive all the nutrition we need to be healthy and thrive we take it every morning primal edge formulated and approved by nico and page of living a primal lifestyle buy it today for just eighty nine dollars click on the primal edge banner on the front page of tfnn.com Hi folks this is Steve Rhodes stay tuned for another great hour of the traders edge heard here at tfnn.com. Yes Gigi thank you for telling me that you showed the TLT the TBT is two times two I know that but the chart pattern is the same it's the only inversion that we've got of the TLT as a chart that's the only reason I use it I wasn't talking about as as an instrument to buy just it as an instrument to do a technical analysis on and then a statement in the den was that Basil Clover CLVS had 50% short interest so short squeeze plus they reported low operating loss an impossible indication of approval for prostate cancer all right well that's you know I mean so it's it's obvious they're stuck up to keep in mind as one of the biotechs that has a good story now I just want to mention to you subscribers if you're listening the screamer trade I had on today if you're fortunate I said to buy it on the dip after a few minutes if you're fortunate enough to have waited and you got it near the near the low that allowed you that very tight to one and one point two percent stop and you're in it and it's now trading a little bit above yesterday's close this is exactly what we wanted to see if you did if you were stopped out you have a choice you could maybe go with the lighter position now I do think it's about to start moving higher we did have one that I took off and now I said I just I didn't want to follow right to this moment but I expected that it would make that peak see you know we're always looking for the fourth highest peak in the chapter methodology and that is bk cc backrock capital invert investment corporation closing mutual fund company we had a 14.96 we had a tight stop of 0.04 1% we got stopped out and then I went from a peak see at 506 it pulled back and I said yep it looks like it wants to make a deal had a choice today be either this one or that one well today this is the screamer it's a 1.9 cent percent at 5.11 it's doing exactly what we wanted unfortunately we're not in it but this is a this is a learning experiment for me I've tried to do it myself I think I'm getting a feel for the way I can do it for subscribers is a little more difficult a lot of more words a lot more pay I think I'm gonna get it right but these screamers are ready they work they just they make up for any tiny loss very quickly so I have a wonderful day I'll see you tomorrow see you for Steve Dave and I'm a Brian check out my opening call my daily newsletter team quite nicely these days and
