The total cross-sectional area of the inlet to the jet engines is 20 ft2. Assume that the flow properties of the air entering the inlet are those of the freestream ahead of the airplane. Fuel is injected inside the engine at a rate of 0.05 Ib of fuel for every pound of air flowing through the engine (i.e., the fuel-air ratio by mass is 0.05). Calculate the mass flow (in slugs/per second) that comes out the exit of the engine. The plane is at standard altitude 50,000 ft and velocity = 2200 ft/s. Would appreciate attack to problem.
