An aircraft has a jet engine mounted on a pylon. the flight velocity is u1= 300m/s. the fully expanded velocity of the jet exhaust is uj= 800m/s. the mass flow rate through the engine is 10 kg/s (neglecting the combustion products). the static pressure at the nozzle exit is 80 kpa. the static pressure at the inlet is 20 kpa. an ambient pressure is measured as p1= 20kpa. the nozzle exit area is 4.0 m^2. determine the thrust via reynolds transport theory.
