Saturated vapor R-410a enters the compressor of a central air conditioning unit at 5 °C. The flowrate of the refrigerant through the compressor is 0.08 kg/s while the required input power is 4kW. The refrigerant leaves the compressor at 60 °C and 2000 kPa. Calculate the following: a) the heat transfer from the compressor to the ambient environment, b) the entropy generation, and c) the isentropic efficiency of the compressor.I
