(a) R-134a flows into an adiabatic compressor of a refrigerator at a rate of 0.5 kg/s. Inlet conditions are a saturated vapor at 24°C. The R-134a leaves the compressor at 1.0 MPa and 60°C. Determine the power used by the compressor and the rate of entropy generation for the compressor. (b) Plot the power consumed and the rate of entropy generation for the compressor for the same inlet conditions and the same outlet temperature, but for outlet pressures varying between 500 kPa and 1400 kPa. What does this indicate about the effect of irreversibilities on the outlet conditions for a compressor?
