Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -20oC with a volumetric flow rate of 0.18 m3/s. Refrigerant exits at 7 bar, 70oC. Changes in kinetic and potential energy from inlet to exit can be ignored.Determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kW.
