A refrigerator uses a compressor that employs R-134a as the refrigerant. Determine the power requirement (W) and volumetric flow rate (ft3/min) for the compressor if the mass flow rate is 2.5 lbm/s, the inlet refrigerant is saturated vapor at a temperature of -10°F, and the exit refrigerant is at a pressure of 120 psia and a temperature of 140°F. Assume that the compressor is adiabatic.
