Question

Air is compressed by a rotary compressor in a steady flow process at a rate of 1.5 0 kg/s. At entry, the air has a specific volume of 0.900 m3/kg and has a velocity of 80.0 m/s. At exit, the air has a specific volume of 0.400 m3/kg and has a velocity of 45.0 m/s. In its passage through the compressor, the specific enthalpy of the air is increased by 110.0 kJ/kg and it experiences a heat transfer loss of 20.0 kJ/kg. Determine: a. The inlet and exit areas of the compressor in m2 b. The power required to drive the compressor in kW
