Refrigerant 134a at -10°c, 1.4 bar, and a mass flow rate of 280 kg/h enters an insulated compressor operating at steady state and exits at 9 bar. the isentropic compressor efficiency is 66.5 %. determine (a) the temperature of the refrigerant exiting the compressor, in °c. (b) the power input to the compressor, in kw (c) the rate of exergy destruction expressed as a percentage of the power required by the compressor. neglect kinetic and potential energy effects and let t0 = 20°c, p0 = 1 bar. round your answers to 3 significant digits.
