Question

Air enters a compressor operating at steady state and is compressed adiabatically from 2 bars, 27°C to 4 bars. The measured work input is 80.6 kJ/kg. Assuming a constant specific heat of 1.01 kJ/kg-K for the air, determine:

(a) The exit temperature (K).

(b) The rate of entropy generation per unit mass of air (kJ/kg-K).
