Question
An airplane engine intakes air. adds fuel to burn the air and exhausts the burnt gases to generate thrust. An airplane flies at 971 km/hr through quiescent air of density 0.736kg/m^3 The intake area of the jet engine is 0.8m^2. A stationary observer on earth estimates the exhaust velocity of the gases at the engine outlet to be 1050 km/hr relative to the aircraft. The engine outlet /exhaust area is 0.558 m^2 and the exhaust gas density is 0.515 kg/m^3.
Starling from the basic integral form of the continuity equation find
a) Absolute exhaust velocity of the gases at the outlet
b) Fuel consumption for the engine
