Air flows at a rate of 0.4 kg/s through an air compressor entering at 6 m/s, 1 bar and 0.85 m^3/kg and leaving at 4.5 m/s, 6.9 bar and 0.16 m^3/kg. the internal energy of the air leaving is greater than that of entering air by 88 kJ/kg, cooling water in the jacket surrounding the cylinder absorbs heat from the air at the rate of 59 kJ/s. find the power required to drive the compressor. *
