Air enters the front of a jet engine at 250m/s. If the intake area is 0.8m2, and the air density(at a height of 5000m) is 0.7 kg/m3, what is the mass flow rate of air into the engine.The air has 2% fuel (by mass) added to it, and after combustion the hot gases exit the rear ofthe engine at 1300m/s. Calculate the thrust of the engineIf the engine is moving forwards at 250m/s, what power is it developing?
