Estimate the rate of heat transfer from the compressor. Assume for air that Cp = 7/2 Rand that enthalpy is independent of pressure. 2.27 Fifty (50) kmol per hour of

air is compressed from Pt = 1.2 bar to P2 = 6.0 bar in a steady-flow compressor. Delivered mechanical power is 98.8 kW. Temperatures and velocities are: T1 = 300 K T2 = 520 K u1 = 10 m.s^-1 u2 = 3.5 m.s^-1
