HW #8, P3 - Analysis of an R-134a Compressor - 5 pts

R-134a enters an adiabatic compressor as saturated vapor at 120 kPa at a rate of 0.30 m3/min and exits at 1.0 MPa. If the isentropic efficiency of the compresor is 80%, determine…

a.) The temperature of the R-134a at the outlet of the compressor.
b.) The power input to the compressor in kW.
c.) Show the process path on a TS Diagram that includes the two phase envelope and all relevant isobars.
