5-2 An air compressor delivers 4.5 kg of air per minute at a pressure of 7 bar and a
specific volume of 0.17 m³ /kg. Ambient conditions are pressure 1bar and specific
volume 0.86 m³/kg. The initial and final internal energy values for the air are 28 kJ/kg
and 110 kJ/kg respectively. Heat rejected to the cooling jacket is 76kJ/kg of air
pumped. Neglecting changes in kinetic and potential energies, what is the shaft power
required driving the compressor?
