Refrigerant 134a at -10°C, 1.4 bar and a mass flow rate of 280 kg/hr enters an insulated compressor operating at steady state and exits at 9 bar. The isentropic compressor efficiency is 82%. Determine (a) the temperature of the refrigerant exiting the compressor, in °C (b) the power input to the compressor, kW and (c) the rate of entropy production kW/K. The surrounds can be taken to be To= 20°C, Po = 100 kPa.
