Air at 300 K, 1 bar enters a compressor operating at steady state and is compressed adiabatically to 1. 5 bar. The power input is 42 kJ per kg of air flowing. Employing the ideal gas model with k 5 1. 4 for the air, determine for the compressor (a) the rate of entropy production, in kJ/K per kg of air flowing, and (b) the isentropic compressor efficiency. Ignore kinetic and potential energy effects
