Air at 290 K, 100 kPa enters a compressor operating at steady state and is compressed adiabatically to an exit state of 420 K, 330 kPa. The air is modeled as an ideal gas, and kinetic and potential energy effects are negligible. For the compressor: a. Determine the rate of entropy production, in kJ/K per kg of air flowing.
b. The isentropic compressor efficiency.
