3.24 An air compressor compresses air with an enthalpy of 96.5 kJ/kg to a pressure and temperature that have an enthalpy of 175 kJ/kg. There are 35 kJ/kg of heat lost from the compressor as the air passes through it. Neglecting kinetic and potential energies, deter- mine the power required for an air mass flow of 0.4 kg/s.
