The 2nd Law of Thermodynamics

Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.16 MPa, and leaves
as superheated vapor at 0.9 MPa and 70◦C at a rate of 0.08 kg/s. Determine the rates of energy transfers by
mass into and out of the compressor. Assume the kinetic and potential energies are negligible.
