Refrigerant 134a enters a compressor operating at steady state as saturated vapor at 0.12 MPa and exits at 1.2 MPa and 708C at a mass flow rate of 0.108 kg/ s. As the refrigerant passes through the compressor, heat transfer to the surroundings occurs at a rate of 0.32 kJ/ s. Determine at steady state the power input to the compressor, in kW.
