Question:

Fifty (50) kmol per hour of air is compressed from P1 = 1.2 bar to P2 = 6.0 bar in a steady-flow compressor. Delivered mechanical power is 98.8 kW, Temperatures and velocities are:
Fifty (50) kmol per hour of air is compressed from

Estimate the rate of heat transfer from the compressor. Assume for air that CP = 7 / 2 R and that enthalpy is independent of pressure.
