Product Compression. I am currently doing some work on compression. I know the flowrate in and the pressure and temperature in, and I know the pressure (and flowrate) out. Can I determine the temperature out? I have tried using P1V1/T1=P2V2/T2, but as V is a function of T (using values from...

This is about how to relate an abstraction of thermodynamics to a real compressor. The difference of the specific heats is called "external work" since in the legendary cylinder holding a pound of air being heated one degree, the spec heat capacity at constant pressure is this much more than...

So like it says. It may be a silly question, but I am doing some reading on jet engines (on Wiki) and I am having trouble finding an explanation as to why we want to increase the pressure of the air before it goes into combustion. Does this just another way of increasing the thrust? Thanks...

Where can i use CFD in Air comressor?

I am designing a sliding vane rotary compressor for a supercharger application on a small horsepower engine, but I am having trouble with the calculations. I have some estimations that I would hope to be correct (or close) but have no way to verify them at this point. One of the toughest parts...

Hello all. I have the following questions regarding the analysis of the performance of a rotary vane compressor. 1) Why can the specific kinetic and potential energy changes normally be neglected? 2) If an adiabatic compression is considered, what is the primary cause of energy loss...

I need to pump a refrigerant in its liquid state (from low to high pressure), and I am wondering if a normal rerfrigerator compressor is capable of doing this. I don't know the internal specifics; if it somehow depends on the compressability of the fluid it's pumping. I would prefer to use one...

In a rotary vane compressor, the vanes constantly move in and out. Does the work required to accelerate the vanes radially outward and then inward cancel out or is the kinetic energy of the vanes lost and completely converted to heat?

What is annulus area in a compressor?

If the compressor in a turbojet is at high temperatures, it will heat up the air while compressing it. Does it have a negative effect on propulsion? If so, then is it because it reduces the efficiency of the burner as well as hampers the intake of air by increasing its pressure delivering...
