4. Air flows steadily at the rate of 0.4 kg/s through an air compressor, entering at 6 m/s with a pressure of 1 bar and a specific volume of 0.85 m3/kg leaving at 4.5 m/s with a pressure of 6.9 bar and specific volume of 0.16 m3/kg. The specific internal SCORE energy of the air leaving is 88 KJ/kg greater than that of the air entering. The heat loss is 59 KJ/§. Calculate the work required to drive the compressor in KW.
