Air flows steadily at the rate of 0.5 kg/s through an air compressor, С P. entering at 7 m/s, 100 kPa pressure and 0.95 m3/kg volume, and leaving at 5 m/s, 700 kPa pressure and 0.19 m?/kg volume. The internal energy of the air leaving is 90 kJ/kg greater than that of air entering. Cooling water in the compressor jackets absorbs heat from the air at the rate of 58 kW. (a) Compute the rate of shaft work input to the air in kW. (b) Find the ratio of the inlet and outlet pipe diameters.
