How do we balance the system? And how do we fix the system of getting more trade people? I think one of the biggest problems again, we've said it a million times, is the stigma that surrounds the skilled trades industry. You know, it's the fact that we've come so far away from saying, hey, you should get into the skilled trades. Because like we said before, you should become a doctoral lawyer, chase that money. Problem is we're pushing people into other industry saying, oh, well no. The high school dropouts, those are the people that get into the skilled trades. I've told this story a million times. My buddy who's an electrician. He's a commercial electrician who works in Ottawa. He's working in a mall. Father and a son walk by and he overhears the father say, this is why you stay in school so you don't become like him. Little does he know my buddy's making great money. He loves his job. So he's doing something that he's passionate about. But people look down upon the skilled trades.


The University International Club, I think it's an amazing institution they have. They just welcome all the people that are new in town, especially the ones that are connected to university and they offer you time and place so you can meet all the internationals but also Danes. So you just feel welcomed. This was also a great idea they had from the University International Club. They invited all the internationals to the Greenlandic House and just a few minutes ago the director gave us a great presentation about the Greenlandic Society, what kind of challenges, problems and what kind of future they will have. When we arrived we just signed up for the newsletter from the University International Club and since then we have really good information on what's going on in town. When is the international play group taking place and would you maybe like to have a look at the Aros Museum? So it's just great that you know from the start on you know what you can do to meet people and to get in contact with internationals and Danes. I am taking language courses but also the University International Club helped me to find the language partner. Her name is Lisa and I'm really in love with her. We meet once a week and we really go for the Danish but also for the culture and stuff. So for example now I know that the Danes are dancing around the Christmas tree and I did that too. It's amazing, it's a lot of fun to get to know all the traditions.


Hey Bears! This is Diana Alvarado with CalTV Sports here in Evans Diamond. Tonight your Golden Bears took on the San Francisco Dawns and kicked things off to a quick start. Lead off hitter number 9 Cameron Eden sent one over the fence on the first pitch delivered by USF pitcher Grant Young, giving the Bears an early 1-0 lead heading into the second inning. Going into the bottom of the fourth, the Bears were down 3-2 but a momentum shift as a result of Sam Wezniak's home run which sparked a pitching change for the USF Dawns and brought the score to an even 3-3. Later in the inning, number 20 Andrew Vaughn kept pace with Wezniak with a 3-run homer. To round out the game, we saw a late inning 2-run homer from number 4 Cole Elvis and a closing appearance from pitcher Armin Saburi. With a 10-7 lead, Cal brought home a victory. Your Bears now hold a record of 10-8. Make sure to support your Golden Bears as they face the reigning national champions, Oregon State this Friday. Thanks for watching, this is Diana Alvarado signing off. Go Bears!


Asako is the mother of a girl named Megumi, whom she raised by herself. In fact, following Megumi's birth, her dad left home and didn't come back. And in the years that followed, the youngster started to ask questions about her father, although she didn't seem to be too affected by his absence. However, as time passed Asako picked up on something quite troubling. Megumi's demeanor had begun to change when she turned 10 years old. The young girl had become increasingly unsociable, in fact, to the point that she was blocking out her mother out at home. As a result, Asako formulated a somewhat bizarre plan to remedy the situation. It seemed that Megumi needed her father. But Asako couldn't just produce him out of thin air. Or could she? A plan was subsequently hatched that saw the desperate mother hire a man named Ishii Yuichi to play the role of Megumi's absent dad. For a fee of around $200 for every few hours of his time, he would adopt the father's identity and come back into their lives, with the girl completely unaware of the truth. And for the next decade, that setup continued. While this may sound completely bizarre to most people in the Western world, relatives for hire are a very real phenomenon in Japan. These businesses provide companionship to those in need. For example, they might be used by individuals who find the thought of attending an event or function alone daunting. And as we'll see, in Japan, someone can be hired for almost every type of situation. The Japanese man we hear about earlier, Ishii Yuichi, sought to capitalize upon this trend when he launched his own business named Family Romance.  The agency and proxy attendance service will be a substitute for someone and will be a service that helps you, reads an explanatory post on the company's website. We receive about 250 requests a month and our customer satisfaction rate is 98%. With those numbers in mind, Yuichi believes that Family Romance has the potential to become even bigger in the future. It is a company that is moving because of the desire to make people's lives better, he writes on the firm's website. We are a venture company presenting new common sense to the world through the web. While Family Romance provides actors for commonplace events such as weddings, its services extend far beyond that. Indeed, Yuichi's company can be called upon in numerous different situations. And one in particular stands out. If a person wants to avoid an angry dressing down at work, they can recruit a stand-in to take the brunt of it. To provide some background, Yuichi explained to The Atlantic in November 2017 that business people in Japan are expected to make a personal apology to an organization if they're responsible for an error. According to him, such meetings usually end with the person dropping down to their knees and asking for forgiveness. However, thanks to Family Romance, that no longer has to be the case. During the interview, Yuichi recalled some of his experiences in those particular situations. Usually, I accompany a salaryman who made a mistake, he said. I take the identity of the salaryman myself, then I apologize profusely for his mistake. Have you seen the way we say sorry? You have to go down on your hands and knees on the floor, Yuichi continued. Your hands have to tremble. So, my client is there standing off to the side, the one who actually made the mistake, and I'm prostrate on the floor writhing around. And the boss is there red-faced as he hurls down abuse from above. Unsurprisingly, Yuichi can often find such moments a little awkward. I, would, feel extremely uncomfortable, he added. I'm just thinking, I'm innocent. I want a point at the actual culprit and shout, he did it. Family Romance's services don't end there, either. In other instances, the company can be called upon by people looking to fix a relationship. According to Yuichi, women who've been unfaithful to their partners have contacted Family Romance to help smooth things over. To pull that off, an actor would play the role of the other man and apologize to the husband or boyfriend. However, to avoid any physical confrontations with the angered spouse, Yuichi uses an ingenious ruse. There's a manual for everything in this company, he explained. We use psychology to determine the optimal outcome. In this case, the standard tactic is to make me look like a Yakuza gangster. And Yuichi's tactics normally lead to a peaceful conclusion. Typically, I arrive with the wife, and the husband is there. And suddenly, I will just bow then deeply apologize, the Family Romance founder added. Usually, the husband will berate me, but because I appear to be a Yakuza, he won't pursue the matter further. Away from these more intense jobs, Yuichi can also play the role of a boyfriend. Although there are boundaries he won't cross. As the business owner explained, this would be a platonic arrangement with no sexual intimacy. And having had plenty of experience as a fake partner, he tried to sum up why ladies wanted to hire him. The women typically say that in a real relationship, you're slowly building trust, Yuichi explained. It takes years to create a strong connection. For them, it's a lot of hassle and disappointment. Imagine investing five years with someone, and then they break up with you. It's just easier to schedule two hours per week to interact with an ideal boyfriend. Meanwhile, the origins of Yuichi's company stemmed from a somewhat unusual situation. Many years ago, one of his single friends needed some help regarding their child's school. He subsequently stepped in, taking on the part of the boy's dad at a crucial meeting. I had a single mother friend, and she had a son, Yuichi explained. He was trying to enter a private school, but they denied him solely because he had no father. I wanted to challenge the unfairness of Japanese society, so I posed as his father. I wasn't successful in that situation, but it inspired the idea for this business. Moreover, that Japanese mindset of treating children differently if they're from a single parent household eventually led Yuichi to his most challenging role. Much like that first job, he was contacted by a concerned mother, but this time there was a key difference, and it would see his skills really put to the test. In fact, it was Asako who reached out to Yuichi for help.  During her child's early years, Asako hadn't foreseen any major issues relating to Megumi's dad being absent. But that would all change, of course. Ever since Megumi was little, she'd asked me where her dad was, Asako told BBC News in November 2018. All she knew was that he had gone soon after she was born, so she blamed herself. However, it wasn't until years later that the Japanese mother noticed the true impact the father's departure had had on her daughter. Indeed, she started to witness worrying changes in Megumi's behavior as she grew older.  The mom eventually found out that this was a result of bullying at school. The stigma of being raised by a single parent had apparently led to this abuse, so there wasn't an obvious solution. At that point, as she started to read about companies such as Family Romance, Asako decided to take some drastic measures to help her daughter. Her plan was to hire someone to play the role of Megumi's father, hoping that would fill the void in her daughter's life. And following a few discussions, she chose Yuichi for the part. I found, Yuichi to be the easiest to talk to, Asako continued. He's very kind and sweet, so I just followed my instincts. My requests were very simple. Firstly, I wanted him to say how sorry he was that he couldn't be in Megumi's life until then. Secondly, I wanted him to listen to whatever she wanted to tell him. With the instructions in place, Yuichi then began to prepare himself for the role of Yamada. Films proved to be the biggest influence in the end, as he didn't have any personal experience of parenthood. From there, Asako put together a plausible backstory, in which Megumi's dad had another family. After that, Asako informed Megumi that her dad wanted to reconnect with them, which led to the first meeting. It was a very complex emotion that was there, Yuichi told to BBC News. She asked me why I hadn't come to see her before, and I felt her resentment. Despite that though, the elaborate plan appeared to work. Yuichi started meeting up with Megumi and Asako each month, in fact, all the while maintaining the persona of Yamada. After a time, Megumi became much happier and more outgoing, the mom said. She loved to talk, she was lively. She even wanted to go back to school, and that's when I thought, this has all been worth it. And Yuichi has continued to play the role of Megumi's father for the past decade. He explained that the job will only come to an end if Asako decides to pull the plug. However, the future threatens a host of potential complications if he keeps up the act. If the client never reveals the truth, I must continue the role indefinitely, Yuichi told the Atlantic. If the daughter gets married, I have to act as a father in that wedding. And then I have to be the grandfather. So, I always ask every client, are you prepared to sustain this lie? It's the most significant problem our company has. Given the possible longevity of a role like this, family romance has a strict policy in place for its actors. In this company, one person can only have five families at a time, Yuichi said. That's the rule. It's not only about secrecy. The client always asks for the ideal husband, the ideal father. That's a very difficult role to maintain. Yuichi proceeded to touch upon his ongoing relationship with Megumi, who completed her high school studies back in 2017. Despite spending so much time with her over the past few years, he said he hasn't lost sight of the fact that this is just a job. With that being said though, the family romance owner still can't escape one particular emotion. It's a business, Yuichi continued. I'm not going to be Megumi's father for 24 hours. It's a set time. When I am acting with her, I don't really feel that I love her. But when the session is over, and I have to go, I do feel a little sad. The kids cry sometimes, Yuichi added. They say, why do you have to leave? In those instances, I feel very sorry that I'm faking it, very guilty. On the subject of complex emotions, Asako's job was arguably even tougher, as she had to maintain the facade at all times back home as well. Nonetheless, Asako has continued to stand by the bold decisions she's made over the past decade. The mother has never forgotten the desperation she'd felt before hiring Yuichi. But in another twist, she's had to face down an additional challenge that threatened everything they'd built together. When the three of us are together, I feel at peace, Asako said of her relationship with Megumi and Yuichi during the interview with BBC News. We talk, we laugh, and we are very kind to each other. He's been in our lives for such a long time now, I would like to marry him and become a real family. Ultimately though, Asako knew that just wouldn't be possible in the end. I have told, Yuichi how I feel, but he told me to my face that he's with us because it's his job, she said. It's very complicated. I'm very aware that he's only with us because we're paying him. As for the secret itself, Yuichi has naturally considered what might happen if Megumi did eventually discover the truth. In his mind, there's a good chance that she wouldn't react too badly. And even in a worst case scenario, the business owners still believe she would appreciate the work he's done. Asako, meanwhile, had one last thing to say on the matter. I know some people think it's foolish to pay money to lie to my own daughter, and to have a pretend father, but I was desperate, the mom added. My situation isn't unique. I'm sure there are loads more surrogate fathers and mothers out there.


From around the globe, it's theCUBE. Covering HPE Discover Virtual Experience. Brought to you by HPE. Welcome to theCUBE's coverage of HPE Discover 2020, the virtual experience. I'm Lisa Martin and I'm pleased to be joined by Parshul Asnani, the global head of the technology business at HPE partner, Tech Mahendra. Parshul, great to have you on the program. Glad to be here, thanks for having me. So tell me about Tech Mahendra, I see on the website abbreviated as TechM, give our audience an overview of Tech Mahendra, what you guys do. Sure, so Tech Mahendra is a digital transformation, consulting and technology services company operating at the intersection of IT, engineering, networks and BPO services. We have about 125,000 people operating in around 90 countries, about 5.2 billion in revenue and have about a thousand customers across key strategy corticals, our largest being communications, media and entertainment and then we have other strong verticals like technology, manufacturing, HLS, BFSI, retail, energy and utilities. So that's broadly what we do be in existence for well over 30 years now. And tell me about your role as the head of the global technology business. What have you seen transpire and evolve over the last few years and especially the last three months with COVID? Sure, no, absolutely. I think, see, we have organized a company around six strategic business units. They are these customer facing business units and I lead the one that focuses on technology and the high tech industry, if you will, based in the Bay Area. And in this business unit, a large part of our business is in some sense a 360-degree relationship with our customers where not only do we sell into our customers, we also sell with and sell through our customers and also buy from them. So in that sense, it's a little different model in which we operate as compared to, say, other verticals that we have like manufacturing or BFSI or healthcare where the relationship is largely customer and a supplier relationship. We have a full-blown 360-degree relationship. It's very unique from that standpoint. And things have, in some sense, dramatically shifted in the last three years, rather three months, where we're saying that the amount of digital transformation which was to happen over the next two years has kind of happened in the last two months. So this is kind of pivoting a lot of enterprises and including the tech sector into an era where we are saying, how do we, the reposition ourselves to bring in more COVID-related solutions, both from a commercial standpoint as well as a humanitarian standpoint to deal with this crisis. So there are tons of changes that are happening out there in the industry as well as in tech, Mahindra as we kind of get ready for COVID and post-COVID. If you look at some of the specific trends that you're seeing during the COVID crisis in the high-tech segment, what are they? So a couple of things have riveted very differently. Supply chain, for example, which is very crucial to high-tech is undergoing, in some sense, a metamorphosis shift. It's undergoing a seismic shift in the way supply chains are kind of reconfiting themselves. You're also seeing customer experience kind of dramatically changing. Another thing that is coming in very, very strongly from a change perspective, it's kind of a storm that is brewing out there, is how do we enable people to work remotely? We at Tech Mahindra ourselves had to enable 80,000 people in India to work remotely in a matter of weeks. And it's by no means an easy task to do, which in a country where working from home is not really a culture. And also where we work out of secured customer premises, even in India, our secure offshore locations in India, and all those people have now to move to their homes and work out in the living rooms and bedrooms. And that was a sizable shift in the way we had to deal with our engagements and with our customers. And so far, so good. And up on board, we have not had any issues. So Harshal, pivoting so quickly as TechM did to get your 80,000 employees in India to be able to work from home, connectivity, all the challenges associated with that, goes hand in hand with your business being able to deliver an exceptional customer experience. Customer experience being an issue that you say is a rising trend amongst your customers. Customer experience and work from home these days go hand in hand, right? Absolutely. I think we also surprised ourselves at the pace at which we could move these 80,000 people to work from home in a matter of days, as I was saying. And without missing any customers, there is a task imaginable in the pre-COVID era. And we also surprised ourselves at the pace at which we could turn around COVID related solutions so quickly with the help of partners like HPE that are today helping us pivot ourselves from kind of old age solutions to the new age solutions to the new normal today. And yeah, of course, and at the same time, we had to ensure that we enabled the customer experience and don't miss a beat on that while we repurpose our people to work from home. It was a challenge and frankly, we surprised ourselves in the way we did it. So Harshal, talk to me about what in these COVID crisis times, HPE and Tech Mahendra are doing together to help your customers accelerate maybe adoption of new technologies that they need to for their businesses to thrive. You know, Shono, that's a great question, Lisa. Let me start by saying that HPE is a very strategic partnership for us. And we see it as coming together of two market leaders to deliver a very differentiated playbook of solutions for our customers. With it's a robust set of products and solutions and edge offerings, edge gateways, converged edge systems and real time analytics combined with HPE's great green lake offers which is around flexible consumption based services which helps align customers IT spend to deliver pretty much everything as a service. We kind of have a very robust partner in HPE and when you combine this with Tech Mahendra's industry domain and technology depth and the systems integration wherewithal that we bring in, it makes for a very potent combination to drive serious value to our customers. And given the COVID situation, we have kind of defined our relationship along three broad vectors based on the mutual synergies and where we believe we can quickly drive value. Firstly, what are the solution white spaces that we want to address together? Secondly, what are the geographies that you want to operate in? And third is what are the industry verticals that we believe we can quickly focus on? So from a solutioning standpoint, there are four broad trust areas that you want to sharply focus on. Firstly, IoT. It's been a strong partnership with HPE, with IoT and we would like to continue that forward with HPEs, no edge offerings and converged edge systems. We have kind of demonstrated the possibilities of IoT with solutions across smart cities, factors of the future, energy and utilities and of course, telecom. And we have some good success stories we already have with HPE that we would like to build on. We have won some four significant smart city projects in India in four different cities of India. And we also, by the way, won the Systems Integrated Award for Edge and IoT from HPE last year and also the SI partner of the year for Asia Pacific for HPE last year. So we would like to continue to build on that. We also already have a COE on IoT set up in Bangalore. It's a very unique COE that we've built up where we have showcasing solutions around smart cities, around IoT and we also brought in Aruba gear as well with solutions around smart campuses, so on and so forth. So that's number one. Number two is data center transformation. As hybrid cloud kind of takes root, a lot of customers are now looking at transforming their data centers as well. And particularly with HPEs GreenLake, it becomes a very strategic commercial tool for us to bring on demand, paper use models, elasticity, kind of the, as I was talking about, the flexible consumption services model, which is so unique today as we help customers reduce their capex and get them to pay by the drink, if you will, that becomes very, very relevant in the COVID times. And last but not the least, our focus is also on network of the future. When I say that our partnership with HPE is really pivoted around 5G, SDNNFE and private LTE solutions. For example, HPE's private LTE network, which is essentially powered by HPE's EL300 and EL4000 Converged Ed Systems. It's kind of augmented by our industrial IoT expertise. And it includes a reintegrated off the shelf industrial IoT application from TechMantra. It's kind of an end-to-end solution that uses the breakthrough innovation such as small sales, EPC, and smart multi-axis edge computing. So we are staying sharply focused on these areas and we started seeing the results. And given the COVID scenario, we have evolved a bunch of use cases very quickly in multiple industry areas. And both from a commercial viability standpoint and also importantly on a humanitarian level, what we can do together. For example, in Italy as the pandemic was raging, as many of you would know, a ship was converted into a hospital, probably a thousand bed hospital. And HPE stepped in and they brought in the Aruba gear to put up network together, the infrastructure and the connectivity to bring together. And TechMantra, which has a rapid response healthcare solution to help with remote patient diagnostics and monitoring kind of brought in that solution along with HPE to bear in Italy as the pandemic was raging. So that's just an example of how we are partnering at multiple levels. We've created a solution around workspace as a service, as remote working becomes a new normal of a joint solution with HPE on that too.  Sounds like you guys have done a great job of as you mentioned in the beginning of our time here, rapidly pivoting within TechMantra. As you said, it actually kind of surprised ourselves to what you were doing with HPE to deploy rapidly in Italy. So I can only imagine helping customers accelerate projects like smart cities and smart factories where suddenly we need sensors on more things. Harshal, I thank you so much for spending time with us on theCUBE today. Exciting topics. We can't wait to see where this goes. No, thank you so much, Lisa, for your time. It was great talking to you. Excellent, my pleasure. For Harshal, I'm Lisa Martin and you're watching theCUBE's coverage of HPE Discover 2020. Thanks for watching.


Hello and welcome to lecture number 2 of this lecture series on turbo machinery aerodynamics. So, in the last lecture we have just had a very quick introduction to this particular lecture series that you are going to undergo and we also had discussion on various topics that we are going to discuss during this course. We had a quick look at the lecture schedule in terms of lecture wise topics which are to be covered and subsequently we also discussed about the different types of machines or turbo machines the so called turbo machines that we are going to take up in this lecture series. I think you must have realized by now the significance of this kind of a course which is relatively very specialized course. The basic reason for this kind of a course being offered is the fact that turbo machines as we know it in either the compressors or the turbines which is what we are going to discuss in this course is extensively used in day to day life. One of the most common application of this being the compressors and turbines used in gas turbine engines in aircraft engines and therefore, compressors and turbines is the turbo machines form one of the most important components of jet engines. Besides this of course, these components are also present in land based power generation units the thermal power plants which use gas turbine engines for generating power. They also have turbo machines like the fans compressors and the turbines which means that there is a substantial or a significant application of all these components which is the reason why such a specialized course is being offered which discusses primarily the aerodynamics associated with the turbo machine components. So, in today's lecture we are going to discuss about the compressors and fans. We will have a quick discussion on the simple aerodynamics of compressors and fans and how is it that we can account for the aerodynamic performance using very simple analytical tools. So, we are going to have a very quick overview of some of these topics. We will also be discussing about some of the analytical methods which are used in very preliminary design analysis techniques which is what one would endeavor before taking up a very detailed component performance or component design. So, in today's class we are going to discuss about the following topics. So, we are going to talk about the thermodynamics of compression. It is very important that we understand the fundamental thermodynamic principles behind compression. We will express the compression process in terms of pressure volume that is p v and temperature entropy T s diagrams of compressors. And subsequently we will take up the compression process and how compression takes place in single stage as well as multi stage compressors. We will express the compression process in terms of the temperature entropy diagrams. And then we will begin our discussion on the basic operation of axial film compressors and fans. Subsequently, we will take up a very important concept which is known as velocity triangle which forms the basic analytical tool for analysis at a very simple design operation which is what one would start off with before taking up detailed component design. We will also be talking about work and compression, how we can calculate the compression ratio in a compressor using the temperature rise across the compressor and so on. So, we will derive an expression for calculating the work that is required for driving a particular compressor for a certain pressure ratio. So, these are some of the topics that we are going to discuss. So, you have seen that we are going to begin our talk with our discussion with very simple analytical methods. And so, we need to understand what is the significance of these analytical tools? Why should we even go for very simple analysis which invariably have a lot of assumptions inherent in them which may or may not be really true in an actual compressor. But, these analytical methods are very important in terms of actual design because this is where an actual design starts. So, when we take up a compressor design exercise, we start the design process using very simple analytical tools. So, basic idea behind carrying out such an analysis is that we can get some idea about what is the kind of power that or work that will be required to derive this particular compressor for a certain pressure ratio. We would also get some estimate about what are the kind of losses that this compressor is likely to incur and therefore, the efficiency of such a compressor system. So, the advantage of this analysis is that it gives you a very quick design optimization process wherein you get a very preliminary design of a compressor and from which you can also estimate the power requirements and therefore, the efficiency and so on. And if that does not really fit in the scheme of things, one can incorporate certain design changes to ensure that the compressor actually meets the specifications for which it is being designed. And so, this is the primary objective of carrying out this kind of a simple analytical technique. And so, which means that a simple aerothermodynamic analysis which basically precedes a detailed component design is something which is required to have a reasonably good prediction of work requirement as well as the efficiency of the compressor. And the main advantage being that this enables very quick design modifications, because if one were to take up detailed design right at the beginning and that detailed design obviously, is much more complicated and it takes a lot of time and effort. And let us say at the end of that exercise we see that the compressor requires certain modifications to meet the design specifications. Then the design turnaround time is quite huge, because it takes a lot of time for carrying out detailed component design. Therefore, a simple aerothermodynamic analysis will give us very quick idea about where this compressor is taking us. If it is a good compressor in terms of efficiency and work requirement, then we can proceed further and take up the detailed design. So, that means that it saves a lot of time in terms of the overall design and optimization cycle. So, that is the basic need for carrying out such a simple aerothermodynamic analysis. So, what we are going to do is that we will begin with very simple thermodynamic concepts, which I presume you would have undergone during some of your earlier courses. We will take a look at a compression process in strictly a thermodynamic sense that is what happens in an ideal thermodynamic compression process and what happens in an actual thermodynamic process. So, that is what we will begin with our discussion on how we can analyze a compressor in terms of its thermodynamic process of compression itself. So, what I have here is a simple representation of a compression process. You can see that on the left hand side, the graph here is expressed in terms of pressure and volume, which is specific volume basically. And you can see three different lines or graphs here 1 to 2 dash, 1 to 2 double dash and 1 to 2 triple dash. Each of them representing a different type of compression process. The first process that you see that is 1 to 2 prime is an adiabatic compression process. An adiabatic compression process is one where the exponent that is involved is p v raise to k here in this case the exponent is equal to gamma, which is the ratio of specific heats. So, this is an adiabatic compression process and what we will see is very soon is that an idealized compression process can be expressed as an adiabatic compression, which is reversible, which means that if you remember from your thermodynamics, a reversible adiabatic process is an isentropic process. So, if the adiabatic process can also be approximated to be a reversible process, then what you have is an isentropic process that is the entropy remains a constant. So, on a temperature entropy diagram one would get a vertical line, which basically indicates that the entropy is a constant. So, this is true for an adiabatic process where k is equal to gamma. So, this is basically a process where we have the power of the product p v raise to k is equal to gamma and that is that represents an adiabatic process. Now, let us take a look at the second process here, where k is equal to 1 that is the exponent is equal to 1, which means that it is p v raise to 1, which is p v is a constant. The product of pressure and volume is a constant and what does that indicate? It basically tells us that pressure the product p v being constant means that this is an isothermal process that is temperature remains a constant during p v is equal to constant process. So, the second process of compression again as I mentioned all these three process that we are discussing is a compression process basically because the pressure is increasing, because compression is accompanied by an increase in pressure and also by a decrease in specific volume. So, here we have one of the processes the first processes, which we discussed was an adiabatic process p v raise to gamma is constant. The second process is an isothermal process because p v is equal to constant. So, because from the state law if you remember p v is equal to r t and. So, since p v is constant the right hand side r t the gas constant is anyway a constant and therefore, temperature also remains constant and that represents an isothermal process. And the third extreme of this is if v is equal to 0 that is if specific volume is equal to 0 you get an isochoric process that is volume is a constant, but you still get the pressure raise and that is the third process. So, out of these three I think the first two that is an adiabatic process and an isothermal process is what is of interest to us. The reason being in an isentropic process as you know if it is reversible you have hardly any losses taking place if it is a reversible process there are no losses. So, the efficiency of the compressor is very high and the second possible process is an isothermal process. You might have studied about intercooling in your thermodynamics course intercooling is a process where at the end of one compression process you cool down the air to its initial temperature before taking of the second compression process and so on. So, number of stages of intercooling can lead to a compression process which is isothermal. Advantage of an isothermal compression is that isothermal compression requires the least work input. You might have seen in the pressure volume diagram area under the curve tells us the amount of work required for this particular compression process. And therefore, an isothermal compression process requires the least work and that is the basic advantage of having an isothermal compression process, but all the actual cycles cannot really be taken up as an isothermal compression because there is an increase in temperature taking place during the process. It is never p v is equal to constant it is always p v raise to k is equal to constant, but for our simplified analysis most of the time we might assume that the exponent is equal to gamma. And therefore, p v raise to gamma is equal to constant that is an adiabatic compression is a much more realistic type of compression process that one might deal with in day to day life. So, let us move forward now. Let us express the same processes on a temperature entropy plot I mentioned that one of the processes has k is equal to gamma which is an adiabatic process and if that is a reversible process then we have an isentropic process. So, that is the first process that is being represented here when k is equal to gamma the compression represents an isentropic compression which is why you have a vertical line because your x axis is entropy. So, this is a constant. So, you have an isentropic compression and in actual cycles you would not really have the compression which is adiabatic. So, you may have gamma which is different from that of ratio of specific heats may be different. So, you may have a non isentropic compression. So, this represents the dotted line actually represents a polytropic process where the exponent is not necessarily equal to gamma. And then we have the other extreme that is 1 2 double prime where k is equal to 1 this is an isothermal process. Therefore, temperature is a constant. So, you can see that the temperature is constant of course, it is non isentropic, but this is an isothermal process and you may also have k is equal to infinity which is basically corresponding to an isochoric process that is a constant volume process. So, this is the thermodynamic representation of compression on a temperature entropy diagram T s diagram what we have seen previously was pressure volume diagram. So, one can express the compression process in either temperature entropy coordinates or in pressure volume coordinates. So, you are going to come up with we will be looking at compression process throughout this course in either of these coordinates either pressure volume coordinates or in temperature entropy coordinates, but most of the time as you would notice very soon we would be usually using the temperature entropy diagram. Basically, because of the fact that it is little easier to visualize adiabatic processes and non or isentropic processes and non isentropic processes on a T s coordinate. And therefore, we will usually be representing the compression process on a T s scale or T s coordinates. Now, what we will do next is that we will also start looking at the compression process itself not just in terms of TV PV or T s diagrams, but also in terms of what happens in an actual compressor and how the pressure rise or temperature rise takes place across rotors and status of an axial compressor. So, before that let us again look at this temperature entropy diagram. So, here we have T s diagram which is what I had shown in the previous slide. Now, in an ideal process as I mentioned we would normally assume the compression process to be this that is k is equal to gamma which is 1 2 prime that is an isentropic process. And an actual compression process is what is represented by the dotted line where k may not be equal to gamma it could be different from it could be a poly tropic process which is 1 2. So, this represents an actual compression process 1 2 ideal compression process is 1 2 prime. So, the deviation of the actual compression process from the ideal compression process is usually expressed in terms of what is known as an isentropic efficiency. So, enthalpy at state 2 prime minus enthalpy at state 1 divided by enthalpy at state 2 minus enthalpy at state 1 represents what is known as an isentropic efficiency of the compressor because that tells us how far is the compression operation from an ideal behavior because if it was an ideal behavior isentropic efficiency would have been equal to 1 and you would have got a vertical line which represents an isentropic process. So, actual compressors are obviously not isentropic. So, the deviation of actual compressors from the ideal compressors is usually expressed as isentropic efficiency of the compressor system. So, we shall be referring to isentropic efficiency very often in throughout the course because that forms one of the basic parameters or performance measures using which we will evaluate the performance of compressors. So, it is very important to understand the significance of isentropic efficiency. So, moving ahead what we will do next is to look at what happens in a compressor rotor and a stator combination as you are aware that a stage of a compressor an axial compressor let us say consists of a rotor followed by a stator rotor is the rotating component stator is a stationary component. So, in a in a compressor if you look at one stage of an axial compressor you would look you would basically have one component which is rotating that is called the rotor this is followed by a stationary set of blades which are known as a stator. So, let us take a look at what happens to the flow as or thermodynamically what happens as the flow passes through a rotor and subsequently through a stator. So, what I have here is a temperature entropy diagram which represents the compression process in terms of let us first look at the static parameters that is we are looking at static temperatures here and static pressures. So, this represents the rotor and then subsequently we have a stator. So, state 1 indicates the rotor inlet state 2 indicates rotor exit state 3 indicates the stator exit. Now, the vertical lines here actually show the isentropic processes that is if the entire compression process was to be isentropic then one would have got a change in temperature from state 1 to state 3 double prime. Now, since there are losses taking place or irreversibility is taking place in the rotor as well as stator we see that the line the compression process is not isentropic it is non isentropic which is why we can see this inclined line which means that there is an increase in entropy which is both across the rotor as well as the stator. So, 1 2 represents the actual compression in the rotor at the exit of which the temperature is T 2 static temperature is T 2 and static pressure is P 2 from state 2 to 3 is the stator at the exit of the stator we have static temperature T 3 and static pressure P 3. Now, if you look at the corresponding isentropic processes 1 2 2 double prime would have been the isentropic compression process the actual process is between 1 and 2. So, what is represented here as x 1 represents the loss of the loss taking place in the rotor because of irreversibilities. Similarly, there is a certain amount of loss taking place in the stator because which is basically the difference between the actual and the isentropic states which is represented by x 2. So, x 1 and x 2 represent the losses taking place in the rotor and stator respectively. Therefore, the total loss taking place in the compressor stage is equal to the sum of the 2 which is x 1 plus x 2. So, what I have represented now is the compression process using static parameters and what we will take up next is to look at the compression process in terms of stagnation parameters as well and you will notice that there are certain differences which you will have to keep in mind when you look at the variation of stagnation parameters. Basically, it is a fact that across stator there cannot be any change in stagnation temperature because we are not adding any energy in the stator unlike a rotor where energy is added. Therefore, it is possible for us to have a change or rather an increase in stagnation temperature in a rotor. On the other hand, the stagnation pressure can be different both in stator as well as rotor. In a rotor you get an increase in stagnation pressure in a stator because of losses taking place in the stator you might end up getting a lower static stagnation pressure. You might have loss of stagnation pressure in the stator and not loss of stagnation pressure in the rotor. In the rotor you have an increase in stagnation pressure as well as stagnation temperature whereas in the stator one has no increase in stagnation temperature and you might have a certain amount of stagnation pressure loss in the stator. So, let us take a look at the temperature and trophy diagram on stagnation coordinates. So, in this particular diagram what is shown here in red line indicates the total parameters. So, the red lines here indicate the total parameters whereas the blue and black lines indicate the static parameters. So, compression begins at state one which is static temperature. This if you add the stagnation dynamic head you have the stagnation temperature. So, T 1 plus C 1 square by 2 C p where C 1 is the absolute velocity through the rotor by 2 C p gives us the rotor inlet stagnation temperature which is T 0 1. And then after this after let us say the rotor entry now the flow proceeds through the rotor. Rotor exit is T 0 2 which is shown here there is a stagnation temperature rise as I mentioned there is a stagnation temperature rise in the rotor. Because there is energy added in the rotor because rotor is driven by an external agent and therefore it is possible for us to get an increase in stagnation temperature in the rotor which is why you see that T 0 2 is greater than T 0 1.  So, I mentioned that in a stator you might have certain stagnation pressure loss because of frictional losses etcetera. But you cannot have a loss in stagnation temperature which is why you have T 0 3 is equal to T 0 2. The stagnation temperature at rotor stator entry and stator exit remain the same they cannot change whereas they can be a stagnation pressure loss taking place in the stator. Similarly, the corresponding velocity components are shown that is T 2 plus C 2 square gives us T 0 2 and similarly T 3 plus C 3 square by 2 C p gives us T 0 3 which is obviously equal to T 0 2. So, what is represented here in terms of what seems to be a rather complicated graph is that the compression process proceeds in stages that is you have certain compression taking place in the rotor you also have certain amount of compression taking place in the stator it is a combination of these two that gives us the overall compression. And so once you understand the basic thermodynamics behind a compression process the rather complicated diagram which you might have seen now will really look quite simple because even though it looks very complicated with all those numbers there with C 1 square by 2 C p and C 2 square by 2 C p and so on. If you understand the logic behind them it is very simple T 1 plus C 1 square by 2 C p gives us T 0 2 and similarly the stagnation temperature is equal to the static temperature plus the absolute velocity square divided by 2 C p. And the fact that there is stagnation temperature rise taking place in the rotor because of energy addition stator there is no change in stagnation temperature because you are neither adding any heat or nor taking out any heat. In the rotor you also have stagnation pressure rise but in the stator you may have stagnation pressure loss which is because of the frictional effects that affect a compressor performance. So what we have seen is the compression taking place in one stage that is in one rotor and one stator. Let us now take a look at what happens as the flow passes through multiple rotors and stators that is you have several rotors and stators in a multi stage axial compressor the one which you had seen in the last class. You may have let us say 15 to 20 stages each of them having one rotor and stator. So when flow passes through these rotors and stators what happens to the flow. So in a multi stage compressor in which is what is represented here in terms of T s diagram you have the rotor what is which is indicated by r and stator which is indicated by s. So what we see is that the at the rotor exit the flow still has substantial amount of kinetic energy this we can convert to static pressure using stators which is why one has we would have stators because at the exit of rotor the kinetic energy is quite high and therefore we can convert that to static pressure. And so what you see here is the solid lines represent the isentropic processes that is the rotor is isentropic and there is isothermal stator and in an actual compressor the rotor is usually polytropic it is not isentropic. But the stator continues to be isothermal because even an actual compressor you still cannot have loss of temperature taking place in the stator. So an actual compression is what is shown here is polytropic compression in the rotor followed by isothermal compression in the stator and that proceeds for several of these compressor rotor stator combinations or stages. And what is shown here by this line here represents the average temperature entropy characteristic that is if you consider all these rotor stator combinations the average of this represents the average behavior of the compressor which has multiple stages of rotors and stator combinations. And so your average temperature entropy varies in a manner which is shown by that particular line. So what we have done so far is to look at the performance of a compressor from a very simple thermodynamic perspective. So let us move a little further now and look at the basic operation of an axial compressor itself how does an compressor operate thermodynamically we know now how it operates. But how does the operation of an axial compressor take place in an actual sense. So we will now look at the operation of an axial compressor itself and then we will discuss what is known as the velocity triangle which is a very important concept. So we will spend some time discussing about that. So an axial compressor as we know consists of usually consists of series of stages and so each of these stage has one set of rotor blades and followed by a set of stator blades. So why do we have a rotor and a stator thermodynamically we have seen the reason why rotor is the component through which energy is added to the compressor. So for compression to take place we should be able to add energy. And why do you need to add energy you need to add energy so that you get an increase in stagnation temperature which is possible only if you add energy you also get an increase in stagnation pressure correspondingly because you are adding energy. So compression can take place only if energy is added to the system and that is why a rotor is required. Then you may wonder why do we need a stator at all why cannot we have only a series of rotors. The reason why we have rotors followed by stators is that at the exit of the rotor we have a substantially high kinetic energy which is present. And therefore if we do not have a stator the next rotor which follows or succeeds the first rotor stage will phase a substantially high kinetic energy that means it has to deal with a very high kinetic energy and therefore designing such a rotor is not an easy task. A stator is meant so that you can diffuse the flow recover static pressure by converting kinetic energy to static pressure decelerated before it hits the second rotor stage and so on. So in a stator we basically recover static pressure by converting kinetic energy to pressure. So that is why we have a stator which follows a rotor and this of course is carried out over several stages of rotors and stators. So as we can see compression process occurs in both rotors as well as stators and because rotor blades have rotating motion present we have two distinct velocity components present. One is the absolute velocity and the other is relative velocity. Absolute velocity is something which is increased as it passes through the rotor whereas the relative velocity decreases which is why it leads to diffusion even in the rotor and so which means that in an compressor stage especially in the rotor because of the rotor rotation itself you have two distinct components of velocity. One is an absolute component of velocity which is the velocity component which one would see if you are let us say observing a compressor from outside the compressor itself that is from an inertial frame of reference. The other velocity the relative component of velocity is one which one would see if you are actually standing on the blade. If you are now standing on the compressor blade and observe the flow you would see the flow coming in at a different velocity because the blade itself is moving at a certain velocity. So that is known as the relative component of velocity in the relative frame of reference. So what we will do is that we will represent the compressor the velocities in terms of what are known as velocity triangles because you now know that there are two distinct velocity components the absolute velocity as well as the relative velocity and you also have the rotation of the blade itself. So there are three distinct velocity components now the absolute component the relative component and the blade speed. So these three velocity components need to be put together and analyzed and that is done using what is known as a velocity triangle. So let us take a look at what we mean by a velocity triangle. So we begin the analysis of axial compressor in an elementary sense using what are known as velocity triangles. So this analysis is carried out are usually at the mean blade height where the peripheral velocity of the blade speed is u and what we do is that we will represent the blade speed by u the absolute component of velocity will be represented by c and the relative component will be represented by v. And so the axial velocity the absolute velocity in the axial direction will be represented by c subscript a where a represents axial and c represents absolute velocity tangential component will be denoted by subscript w w stands for world. So absolute velocity in the world direction or tangential direction would be c w relative component of that is v w. We will denote alpha as the angle between the absolute velocity and the axial direction and beta will be the velocity of the angle between the axial direction and the relative velocity. So alpha is the angle which is the angle between absolute component of velocity and the axial direction beta is the angle between the relative component of velocity and the axial direction. So these are the notations that you need to keep in mind c is for absolute velocity v is for relative velocity and subscript a is for axial w is for tangential or world and what we will see later on is subscript r which is for radial component. At the moment we will not worry about radial component because we are doing a simple two dimensional analysis. Alpha represents the absolute angle, angle between the absolute velocity and the axial direction and beta represents the angle between the relative component and the axial direction. So with these notations in mind let us now look at how we can construct a velocity triangle for a rotor. So let us look at a typical rotor or stator combination one stage one represents the station at the rotor inlet and two represents the station at the rotor exit and three is which is also the stator inlet three represents the stator exit which also happens to be the second stage rotor inlet. So these are the three different stations that we are looking at one for rotor inlet two is for rotor exit or stator inlet three is for stator exit which will be the rotor inlet for the next stage and you can see the rotors and stators the way they have been arranged. Now this is a compressor blade. So compressor blade will basically rotate in this particular direction this is the direction of rotation of the compressor blade or rotor because it is doing work on the flow and like a turbine blade which we will see later the direction of rotation is the other way around because the flow does work on the rotor here in a compressor blade work is done on the flow and therefore this is the direction of rotation of the rotor. Now let us look at the velocity components one by one. So this represents the green line arrow which has shown here is the vector representation of the relative component of velocity at the inlet of the rotor that is v 1. Now this is at an angle of beta 1 at the rotor inlet. Now how does beta 1 come? Beta 1 is because this is the angle which the relative component makes with the axial direction. Now vectorially we know that the difference between the relative component absolute component is primarily because of it is basically because of the blade speed u. So vectorially the absolute velocity c should be equal to u plus w that is blade speed plus the relative velocity. Therefore we have the vectorial sum of the two that is c which is the absolute velocity should be equal to u plus w. u is the in this direction because rotor is rotating in this direction. So u is given by this direction v 1 is basically the velocity which is at a tangent to the leading edge of the blade camber. So at the blade camber angle if you draw a tangent at the leading edge that is that basically gives us the direction of the relative velocity. So if you add up all the three vectorially the direction of the absolute velocity c 1 is indicated by this red arrow here. So this shows us the velocity triangle at the inlet of the rotor and now let us look at what happens as the flow exits the rotor. The flow will exit the rotor the relative component of flow will exit the rotor at a in a direction which is standard initial to the trailing edge of the blade. And therefore we have v 2 which is the absolute relative velocity at the trailing edge of the rotor leaving the rotor at an angle of beta 2. And similarly we can now construct the velocity triangle at the trailing edge of the rotor at the exit of the rotor c 2 is leaving at an angle of alpha 2 alpha 2 is the angle between the absolute velocity c 2 and the axial direction. And the complete velocity triangle at the exit is given by this that is c 2 is equal to u plus v 2. Now remember we are doing this for one particular radial location usually the mid span. And therefore there is no variation of u the blade speed remains the same between the inlet and exit of the rotor. Across the stator obviously there is no relative component of velocity because the stator blades are stationary. And so c 2 is the absolute velocity which enters the stator and it leaves the stator with a velocity of c 3 at an angle of alpha 3. So, this completes the velocity triangle for this stage that we are discussing which is a combination of rotor set of rotor blades and a set of stator blades. We will now look at the velocity triangles that we have just seen in little more detail. We will also look at the other components of velocity which are involved like the axial velocity and the whirl velocity of the tangential velocities. So, if we put together both these velocity triangles which we have seen one is at the rotor inlet and the other is at the rotor exit. We will get a combination of velocity triangles and you have seen that as a rotor inlet and rotor exit the velocity component which is common to both of them is the blade speed that is u. So, if you combine both these velocity triangles what we see here is the this velocity triangle which I am now indicating which constitutes which is constituted of c 1 the absolute velocity at rotor inlet v 1 which is a relative velocity at rotor inlet and u that is the velocity triangle at the inlet of the rotor. The corresponding angles are alpha 1 for the absolute velocity beta 1 which is for the relative velocity. At the trailing edge of the rotor we have c 2 and v 2 u remains the same. So, we overlap both these velocity triangles one over the other. So, we have c 2 and v 2 alpha 2 is the absolute angle at the rotor exit and beta 2 is the angle which the relative velocity v 2 makes with the axial direction. So, both these velocities put together is what is shown in this sketch. Let us also look at the other velocity components. The axial component of the absolute velocity is indicated by c subscript a which is also known as the axial velocity and correspondingly we have the tangential velocities that is the component of these velocities in the tangential direction or in the direction of u. The component of c 1 in the tangential direction is given by c w 1 the component of c 2 and in the tangential direction is c w 2 similarly we also have v w 1 and v w 2. So, the difference between c w 2 and c w 1 is what is represented here and indicated as delta c w. This is the net change in tangential velocity across a rotor. So, as we will see very soon that this component of velocity will come up in our power calculations. What is the amount of power required to drive compressor rotor will primarily depend upon the change net change in the tangential velocity. So, delta c w will tell us will give us an indication about how much is the power required to drive such a compressor this particular compressor rotor. So, let me just quickly recap what we discussed about the velocity triangle because we are going to use velocity triangles throughout this course not just for compressors we will use it also for the other components like the centrifugal compressors and turbines and so on. So, it is very important that we understand clearly how a velocity triangle is constructed. So, velocity triangle as I mentioned basically consists of three components of velocities the blade speed that or the peripheral velocity as you might read in some books which is indicated by or denoted by symbol u. Then we have the absolute component of velocity which is denoted by c and the relative component of velocity which is indicated by v. So, vectorially c is equal to u plus w because the difference between the relative velocity and the absolute velocity is because of the rotation of the blade itself and that is why you have two distinct velocity components one in the absolute frame of reference and the other in the in a relative frame of reference. And so, c vectorially is equal to v plus u and that forms the basis for construction of the velocity triangles. And the direction of u obviously comes from the fact that it is a compressor blade and so that determines the direction of u and once the direction of u is known the inlet angle of the rotor which is given by beta 1 is determined because that is the angle at which the relative component of flow is going to enter the blade that is tangentially at the leading edge of the blade. And so, once that is fixed you have the rotor inlet velocity relative velocity and then the blade speed and both of them put together gives us the absolute velocity as well. So, from this concept that you have you can also construct the velocity triangle at the trailing edge of the rotor and across the stator as we know there is no relative component. So, it is just absolute flow which is absolute velocity which decelerates. Now, the other important thing that you need to notice is that what happens to these velocity components as they move from the rotor to the stator. So, if you go back to the velocity triangle which I had shown the combination of the two what you see is that in a rotor there is a decrease in the absolute velocities c 1 is the absolute velocity at the inlet there is an increase in absolute velocity at the other. The exit of the rotor you can see that c 2 which is basically the absolute velocity leaving the rotor is higher is greater than c 1. On the other hand if you look at the relative velocities v 1 is the relative velocity at the inlet and v 2 is the relative velocity at outlet. So, you can see that v 2 is less than v 1. And therefore, in the relative frame of reference there is a decrease in velocity from v 1 to v 2 and that constitutes to diffusion taking place in the rotor. And in the stator as you have already seen c 3 which is the stator exit absolute velocity is indeed less than c 2 and therefore, there is anyway deceleration taking place in the stator as well. So, the diffusion process as we have seen even before this is not similar is something which takes takes place both in the rotor as well as in the stator. And even thermodynamically we have seen how the diffusion takes place or compression takes place in a in a compressor across a rotor and a stator. In a rotor you add energy to the flow which is why it leads to increase in stagnation temperature and stagnation pressure. In a stator obviously, there is no energy addition and so there is no increase or no change in stagnation temperature, but usually because of losses there could be some change in stagnation pressures across a stator. So, velocity triangle is the starting point for any simplified design and optimization analysis. And before one takes up a very detailed analysis and detail design of compressor stage it is the velocity triangle from which the entire design exercise begins. And I have also mentioned about the significance of the simplified two dimensional analysis in the design cycle. The fact that simplified design gives us a very quick design turnaround and optimization can be carried out much quickly if we are restricting our design initially to a simplified two dimensional design before taking it to a detailed component design which is much more complicated and time consuming. So, the significance of simplified two dimensional analysis lies in the fact that it is required for us to estimate the work requirements of the compressor gives us some idea about the efficiency that the compressor is going to give us and the fact that it is much simpler to carry out as well as the design whole design cycle takes much shorter time. And if there are optimization techniques to be taken up before the detail design is taken over a simple two dimensional aerothermic analysis gives us a much better analysis at this stage. Now, let us look at what happens as the flow passes from a rotor through a stator what happens to the properties of the flow as it moves from a rotor across to a stator. Now, I have plotted here three different properties one is the enthalpy the other is the absolute velocity and the third is the static pressure. Now, these three distinct lines that are shown here that is state one here represents the rotor inlet and state two represents rotor exit or stator inlet and state three here represents the stator exit. So, as the flow moves from the rotor inlet to the exit there is a change in the enthalpy the stagnation enthalpy of the total enthalpy changes there is an increase in stagnation enthalpy as the flow proceeds from across the rotor this is because of the fact that there is energy added in the rotor and that leads to an increase in stagnation enthalpy. In the stator on the other hand there is no change in stagnation enthalpy because there is no energy added or removed in the stator. On the other hand if you look at the absolute velocity absolute velocity C 1 the inlet of the rotor and we have seen in the velocity triangle that there is an increase in absolute velocity as it passes through the rotor and therefore, C 2 is greater than C 1 absolute velocity at the rotor exit is greater than the absolute velocity at the rotor inlet. In the stator there is a deceleration taking place that is C 3 is now less than C 2. So, there is a decrease in absolute velocity as it passes through the stator static pressure increases all through that is in the rotor as well as in the stator and we have seen this in the T s diagram the temperature entropy diagram that I had shown earlier on that there is an increase in static pressure taking place in the rotor as well as the stator. So, this is how the properties changes as the flow passes from the rotor across as the flow moves across the rotor and across the stator. So, there is a change in all these properties stagnation enthalpy absolute velocity stagnation pressure. In fact, I have not shown that here stagnation pressure increases in the rotor in the stator in an ideal case it remains constant, but in actual compressor one would have a decrease in stagnation pressure in the stator because of losses taking place in the stator. So, this is just to demonstrate how the properties vary as it moves through rotor and stator. Now, let me quickly recap our discussion in today's lecture. We started our discussion today with some amount of discussion on the significance of simplified aerothermodynamic analysis and then subsequently we discussed about how we can represent a compression process in a thermodynamic sense in pressure volume as well as temperature entropy plots and we have seen that compression can be either adiabatic or isothermal or it could be polytropic. And then we looked at the compression process taking place in a single stage compressor across a rotor and then a stator. And then we looked at the compression process that takes place in a multi stage compressor that is across multiple rotors and stators how we can analyze of the compression process in a thermodynamic sense. After that we spent some time on discussion about how we can represent the velocity components across a rotor and a stator in terms of velocity triangles. And velocity triangles as I mentioned forms the starting point of design exercise where one would like to construct velocity triangles across a rotor and stator and see how the properties vary. So, these were some of the topics that we had discussed in today's lecture. We will continue with some of these topics in the next lecture as well where we will discuss basically about work and compression taking place in a compressor and subsequently we will begin with some two dimensional analysis and performance parameters which are used in analysis of axial compressors. We will also spend some time on discussion of what are known as cascades which are basically testing methods used for simplified two dimensional analysis. So, we will discuss some of these topics in the next lecture which would be lecture number 3.


What you are trying to do is stifle half of the population and take us back to 1400 years ago where I know you're not ashamed to say you've mentioned it very lightly today, harsh punishments, but I know you're sully for the Hadoop punishments. You're even for child marriage, which is crazy, but- This is gish-galloping. You want to bring up this topic and not give me a chance to respond. So yeah, I completely disagree with your characterization. It's just a right-wing bigoted characterization. Daniel, first of all, you can't equate make-guarding to the hijab. That's also an unfair corresponding thing. How? That doesn't work. But also, you're saying that you're going to make women happier by veiling them. Tell me, how is a happier marriage going to occur when a woman is forced to do something she doesn't want to do? An unhappy wife does not equal a happy marriage.


Hi everyone, Joe for JaspysCaseBreaks.com coming at you with 2020 Tops Triple Threads Baseball 9 box intercase pick your team at number 7 big thanks all of these folks right here for picking their teams for making this happen really appreciate it There you are. There's the first part of the list right there is the next part of this right there You do see some rnb's right here random number blocks. We did that randomizer in a separate video So there are the results here, so it works just like our number block breaks But only for those teams and only for that break right there not Tyler Brenner brought up a great question What happens if we pull a mystery redemption right usually the mystery adeptions they don't have a team assigned to him So they'll they'll go to one person in the break right so for that instance if that happens We're gonna randomize the team list and if the team lands on a number block spot Giants, right? And say let's say we end up with the Giants on top in that randomizer Then it'll go to spot zero because it's the redemption redemptions go to go to number zero So that's how we're gonna do it. All right, so let's pop this open right here It's the fresh case of triple threads baseball And it's here right there. I marked at top and bottom So I'm gonna select a die right here I'll select a nice Dodger blue die and we'll go one two three for the top and four five six for the bottom And it's gonna be five it's gonna be the bottom So there's the bottom right there And there's pick your team eight right there, which is in the store now.
