Q17
The inlet temperature of an air compressor is T₁=300°K and the outlet temperature is T2-500°K. The compressor operates at a mass flow rate of 0.093kg/sec and the heat lost during the compression is 10kJ/kg. Assume that the air is an ideal gas with Cp=1.004 kJ/(kg°K). Calculate the mechanical power needed to be provided to the compressor shaft. Present your answer in kilo- Watts (kJ/sec).
