Refrigerant 134a enters a compressor with a mass flow rate of 15 kg/s with a velocity of 10 m/s. The refrigerant enters the compressor as a saturated vapor at 10°C and leaves the compressor at 1400 kPa with an enthalpy of 281.39 kJ/kg with a negligible velocity. The rate of work done on the refrigerant is measured to be 380 kW. If the elevation change between the compressor inlet and exit is negligible, determine the rate of heat transfer associated with this process, in kW.
