Refrigerant 22 enters an insulated compressor operating at steady state as saturated vap or at -16 C with a mass flow rate of 1.5 kg/s. Refrigerant exits at 7 bar, 70 C. Changes in KE and PE from inlet to exit can be ignored. Determine: (a) the volumetric flow rates at the inlet and exit, each in m^3 /s (b) the power input to the compressor, in kW
