What is pressure compounding?
Pressure compounding is a method used in steam turbines to improve efficiency by dividing the pressure drop across multiple stages. This involves passing steam through a series of turbine stages, with each stage operating at a different pressure level. By reducing the pressure drop across each stage, pressure compounding helps to extract more energy from the steam and increase the overall turbine efficiency.
Does the cells volume increase when a cell divides?
Yes, the cell's volume typically increases before it divides. This growth phase is known as interphase, and during this stage, the cell accumulates the necessary nutrients and organelles to support division. Once division occurs, the cell splits into two daughter cells, each with its own original volume.
What happens if stroke volume increases?
If stroke volume increases, more blood is pumped out of the heart with each contraction. This results in an increase in cardiac output, which is the amount of blood pumped by the heart in one minute. An increase in stroke volume can also lead to a drop in heart rate to maintain overall cardiac output.
When Increasing end-diastolic or end-systolic volume will increase stroke volume.?
Increasing end-diastolic volume (EDV) enhances stroke volume due to the Frank-Starling mechanism, where greater ventricular filling leads to stronger contractions. Higher end-systolic volume (ESV) can also increase stroke volume when it results from reduced afterload or increased contractility, allowing the heart to eject more blood with each beat. Thus, both EDV and ESV can influence stroke volume, primarily through changes in the heart's filling and pumping efficiency.
When the volume of a confined gas remains the same the pressure will increase if the blank increases?
Temperature. Think about it, if the molecules start heating up they start vibrating more, need more space for themselves, expand, and ultimately increase the pressure. PS I'm a PhD chemical engineer...
What is a stage of an impulse turbine?
In an impulse turbine, the stage is a set of moving blades behind the nozzle. In a reaction turbine, each row of blades is called a "stage." A single Curtis stage may consist of two or more rows of moving blades.

What does steam do to a turbine?
Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using types of steam turbine 1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs. in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases. very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
Why are number of compressor stages more than turbine stages in a jet-engine?
Flow does not like the pressure gradient it sees going into the compressor and is therefore, more likely to separate (causing flow separation). Therefore, a more subtle increase in pressure through each stage is needed in the compressor. The turbine does not see this problem.
What happens to the surface volume of a cube if the length of each edge is doubled?
the volume increase 8 times
Why turbine blades are largenr in size at exhaust end?
Because the steam expands as it passes through the turbine. The steam velocity through the turbine is constant from steam chest to exhaust hood (though it changes in each stage). Thus, the space needed for the steam to expand needs to be expanded to correspond with that expansion of the steam.
Why might a small increase in the demensions of an object cause a large change in its volume?
A small increase in the dimension increases the volume dramatically because the increases are all multiplied by each other. A balloon is a great example of volume increasing rapidly.
Parts of the turbine?
Can you please send to me Turbine parts and function of each part shortly?
When the pressure of a gas at a constant temperature is increased the volume of a gas?
Volume and temperature are directly proportional to each other and so when temperature is increased the volume also increase and vise virsa
