Airat 101 kPa and 25 C enters a compressor with negligible velocity and is discharged at 350 kPa and 40 C through a pipe of 0.1 m area. The steady state mass flow rate is 10 kg/s. The power input to the compressor is 450 kW. Determine the change in enthalpy (in kJ) and the rate of heat transfer (in KW) Assume air is an ideal gas, specific heat capacity at constant pressure is 1 kJ/kg-K, and molecular weight is 29 kg/kmol.
