Question

Dry atmospheric air enters an adiabatic compressor at a 20°C, 1 atm and a mass flow rate of 0.3
kg/s. The air is compressed to 1 MPa. The exhaust temperature of the air is 70 degrees hotter
compared to the exhaust of an isentropic compression.
Determine,
a. The exhaust temperature of the air (°C)
b. The volumetric flow rate (L/s) at the inlet and exhaust of the compressor
c. The power required to accomplish the compression (kW)
d. The isentropic efficiency of the compressor
e. An accounting of the exergy entering the compressor (complete Table P3.9) assuming that the
dead state is the same as State 1 (dry atmospheric air)
f. The exergetic efficiency of the compressor
