Glossary Differential head. We cannot tell you what discharge head a pump will provide unless you tell us the suction head (the head at the pump inlet). Think of a pump as adding head to your system. For example, imagine a pump that adds 20m head. If the head at the pump inlet is 5m then the discharge head will be 25m. The amount of head that the pump adds to the system is called the differential head. So, what we need to know is not what discharge head you require, but how much head would you like the pump to add to your system.

What is a differential in cars? In cars a differential is needed so that the wheels can Turn around be it Left or Right. By simple rules of Distance and Speed we can find out that the outer wheel of the car has to cover more distance than the inner wheel of the car and therefore needs to turn Faster.

What is head? The total head at zero flow is the maximum head also called the shut-off head, the total head decreases as the flow increases. The plot of total head vs. flow for a centrifugal pump is very typical and it looks like this: Figure 6 Typical curve of total head vs. flow for a centrifugal pump. To buy the correct pump for your application you first have to know what total head you need and at what flow rate.

Differential gear Each wheel axle is attached to a differential side gear, which meshes with the differential pinions. On a straight road the wheels and the side gears rotate at the same speed, there is no relative motion between the differential side gears and pinions, and they all rotate as a unit with the case and ring gear.

Purring or Roaring? The Often Forgotten Differential Service All vehicles have some form of a differential. If you have a front-wheel drive vehicle, the differential is located in the front and is often called the transaxle. However, the transaxle shares the same fluid as your transmission fluid, so there’s no differential fluid for you to change.ou can check your transmission fluid, and your front differential fluid would be that same fluid.”. If you have a rear-wheel drive car, the differential is located in the back. If your car is four-wheel drive, you will have three differentials — one in the front, one in the back and one in the center of vehicle.

Compensating differential Wage differential is a term used in labour economics to analyze the relation between the wage rate and the unpleasantness, risk, or other undesirable attributes of a particular job.ne can also speak of the compensating differential for an especially desirable job, or one that provides special benefits, but in this case the differential would be negative: that is, a given worker would be willing to accept a lower wage for an especially desirable job, relative to other jobs.

- Time-Price Differential. A method whereby a seller charges one amount for the immediate cash payment of merchandise and another amount for the same item or items when payment is rendered at a future date or in installments. The immediate payment price is called the cash-price; the later price is known as the time-price or credit-price.

Shift Differential Policies: Exploring the Options The shift differential premium is typically lower than the standard premium because the employee is already earning a higher base rate for working a non-fixed schedule. Pros. The company does not have to pay a significantly higher schedule premium, but retains the flexibility to react to immediate staffing needs.

Differential signaling Differential signaling. Differential signaling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals, each in its own conductor. The pair of conductors can be wires (typically twisted together) or traces on a circuit board.

Clinical Mimics of Lymphoma Although affected patients present with signs and symptoms of malignant lymphoma, histologic features suggest a benign process [74, 76]. The clinical course is malignant, however, and clonal T-cell populations can be identified, so the disorder is now properly classified as a T-cell lymphoma.

How Master Cylinders and Combination Valves Work Pressure Differential Switch. The pressure differential valve is the device that alerts you if you have a leak in one of your brake circuits. The valve contains a specially shaped piston in the middle of a cylinder. Each side of the piston is exposed to the pressure in one of the two brake circuits.he pressure differential valve is the device that alerts you if you have a leak in one of your brake circuits.

What is semantic differential scale? Semantic differential is a type of a rating scale designed to measure the connotative meaning of objects, events, and concepts. The connotations are used to derive the attitude towards the given object, event or concept. Osgood's semantic differential was designed to measure the connotative meaning of concepts.

CENTRIFUGAL PUMP SYSTEM TUTORIAL Static head. Webster’s dictionary definition of head is: “a body of water kept in reserve at a height”. It is expressed in terms of feet in the Imperial system and meters in the metric system. Because of its height and weight the fluid produces pressure at the low point.

Compound Motors This type of motor is called a differential compound because the polarities of the shunt field and the armature are opposite. The cumulative compound motor is one of the most common DC motors because it provides high starting torque and good speed regulation at high speeds. Since the shunt field is wired with similar polarity in parallel with the magnetic field aiding the series field and armature field, it is called cumulative.

Microscope Glossary Generally this term is used in describing a high power (compound) microscope. With a low power microscope the term generally used is stereo head because, unlike the compound microscope, the stereo has a separate objective lens for each eyepiece lens, producing two independent paths of light, one for each eye.

Static Head Static Head. Swan, C. The static head, sometimes referred to as the pressure head, is a term primarily used in Hydraulics to denote the static pressure in a pipe, channel, or duct flow. It has the physical dimensions of length (hence the term head) and represents the flow-work per unit weight of fluid.
