Air enters a control volume operating at steady state at 1.2 bar, 300 K, and leaves at 12 bar. 440 K, with a volumetric flow rate of 1.3 m3/min. The work input to the control volume is 240 kJ per kg of air flowing. Neglecting kinetic and potential energy effects, determine the heat transfer rate, in kW. Evaluate the properties of air using variable specific heats.
