Air modeled as an ideal gas enters an insulated compressor at a temperature of 300 K and 100 kPa, and leaves at 600 kPa. The mass flowrate of air entering the compressor is 50 kg/hr, and the power consumed by the compressor is 3 kW. (Rair = 0.287 kJ/kg-K, k = 1.4, cp = 1.0045 kJ/kg-K, cv = 0.718 kJ/kg-K) Determine the isentropic exit temperature (Te,s) of the air in [K]. Determine the actual exit temperature (Te) of the air in [K]. Determine the isentropic efficiency of the compressor. (Answer: ηc,s = 93.3%) Determine the rate of entropy generated through the compressor in [kW/K]. (Answer: Ṡgen = 0.000397 kW/K)
