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.
Model the earth as a sphere with a diameter of 8,000 miles. Using 14.7 psia as the average pressure at the earth's surface and ignoring variation in g with altitude, estimate the weight of the earth's atmosphere in lbf, and its mass in lbm.
