Air enters a compressor at 100 kPa and 25 ⁰C. It is compressed to 2 MPa and exits the compressor at 540 K. The compressor is at a higher temperature than the surroundings, therefore 140 kJ is lost to the surroundings (as heat) per kg of air flowing through the compressor. You can neglect the kinetic and potential energy. (a) What is the reversible work? (answer in kJ/kg, as a negative number) (b) What is the irreversibility rate? (answer in kJ/kg)
