Refrigerant 134-a is compressed in a two stage compressor. It enters the first stage of the compressor as saturated vapor at -10 degrees C and leaves 900kPa and 60 degrees C. It then enters the second stage compressor as saturated vaport at 900kPa and leaves at 1.4 MPa and 80 degrees C. The mass flow rate of the refrigerant through both stages is 3 kg/s. If the total heat loss from the compressor per unit mass of the refrigerant is 20kJ/kg if the refrigerant, what is the total power input to the compressor?
