Air enters a compressor operating at steady state at 1 atm. with a specific enthalpy of 290 kJ/kg and exits at a higher pressure with a specific enthalpy of 1023 kJ/kg. The mass flow rate is 0.1 kg/s. If the compressor power input is 77 kW. Neglect flow kinetic and potential energy effects. What is the compressor rate of internal irreversibility (kJ/kg-K) and its isentropic efficiency? Be careful and look up the meaning of isentropic efficiency (emphasis on "isentropic").
