Air enters a device operating at steady state at 18 bar and 572 K, and leaves at 1.5 bar and 520 K with a volumetric flow rate at the exit of 1.6 m 3 /s. The rate of heat transfer to the air is 350 kJ/kg. Neglecting kinetic and potential energy effects, determine the: a. Power developed in kW Ans. 649.7 kW b. Volumetric flow rate at the inlet in m 3/s.
