Refrigerant 134a enters a compressor operating at steady, Ask an Expert

Academics

Refrigerant 134a enters a compressor operating at steady state as saturated vapor at 0.12 MPa and exits at 1.2 MPa and 70oC at a mass flow rate of 0.108 kg/s. As the refrigerant passes through the compressor, heat transfer to the surrounding occurs at a rate of 0.32 kJ/s.

Determine at steady state the power input to the compressor, in kW.
