Air, modeled as an ideal gas, is compresses at steady state from 1 bar, 300 K, to 5 bar, 500K, with 150 kW of power input. Heat transfer occurs at a rate of 20 kW fom the air to cooling water circulating in a water jacket enclosing the compressor. Neglecting kinetic energy and potential energy effects, determine the mass flow rate of the air, in kg/s.
