Consider the adiabatic compressor from a refrigerator that uses refrigerant R-134a as the working fluid, flowing at 0.05 kg/s. The refrigerant enters the compressor as a saturated vapor at a pressure of 0.14 MPa. The pressure of the refrigerant at the exit of the compressor is 0.8 MPa. Please interpolate for this problem where needed.

a. If the compressor is isentropic, what is the exit temperature?
b. What is the minimum amount of power (work) that this compressor might theoretically use?
c. If the isentropic efficiency of the actual, non-ideal, compressor is 0.85, what is the actual amount of power (work) that this compressor requires?
d. What is the entropy generated by this device? Assume that the compressor is adiabatic.
