Question: You ve been given a task of evaluating the performance of a compressor. Air is compressed from a temperature of 1 5 . 0 oC

Youve been given a task of evaluating the performance of a compressor. Air is compressed from a temperature of 15.0 oC and local atmospheric pressure to a final temperature of 326 oC and final pressure of 409 kPa gauge. The mass flow rate of the air is 6.83 kg/s and it remains constant. Assume the air has constant specific heat capacity Cp of 1.065 kJ/kg.K, and Cv of 0.730 kJ/kg.K. The compressor is not very well insulated and 3.1kW of heat is lost through the compressor housing at a boundary temperature of 85oC.Assume negligible changes in kinetic and potential energy of the air. The local atmospheric pressure is 100.88 kPa. Now estimate the rate of entropy generation (kW/K) while the air is compressed. (Answer must be in 2 decimals)
