Refrigerant 22 enters an insulated compressor operating at steady state as saturated vapor at - 16oC with a mass flow rate of 1.5 kg/s. Refrigerant exits at 7 bar, 70oC. 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
