Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.14 mpa and leaves as superheated vapor at 0.8 mpa and 60°c at a rate of 0.064 kg/s. determine the rates of energy transfers by mass into and out of the compressor. assume the kinetic and potential energies to be negligible. the enthalpies of refrigerant-134a at the inlet and the exit are 239.19 kj/kg and 296.82 kj/kg, respectively
