Air is compressed from 1 bar and 27c (state 1) to 2.1 bar (state 2) in an axial flow compressor. work required for the compression process is 94.6 kj/kg. heat transfer of 14 kj/kg occurs from the compressor to the surroundings at an average surface temperature of 40c. assume that the surrounding pressure is 1 bar and temperature is 20c. consider variable specific heats for air. molecular weight of air = 28.97 kg/kmol. (a) calculate temperature (k) of air at the compressor exit. (b) find the exergy destroyed (kj/kg) during the compression process using entropy generation. (c) perform an exergy accounting of the compressor. answers: (a) 380 k; (b) 20.5 kj/kg
