Air at 12 psia and 60F enters the jet engine of an aircraft flying at a velocity of 500 ft/s. Inlet area of the engine is 4 ft2. Exhaust gases leave the engine with a relative velocity of 900 ft/s. The fuel flow rate is only 2% of the mass flow rate of the air. Calculate the thrust force developed by this engine. Also, determine the thrust horsepower.
