Compressor exit Temperature.

  1. Jan 27, 2009 #1
    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 Perry's) I have ended up in iterative cycle in which the exit T is oscillating increasingly wildly with time.

    What is the best approach to these calculations?

    Thanks in advance.

    The "best" approach definitely depends on the type of compressor and the process being undertaken.

    If you want a place to start, you can look at the T-dS equations for isentropic flow with constant specific heat to come up with:
