3. Air flows steadily at the rate of 0.5 kg/s through an air compressor, entering at 7m/s speed, 100 kPa pressure and, 0.95 cu m/kg specific volume, and leaving at 5 m/s, 700 kPa, and 0.19 cu m/kg. The internal energy of the air leaving is 90 kJ/kg greater than that of the air entering. Cooling water in the compressor jackets absorbs heat from the air at the rate of 58 kW. Compute the work in kW. *
