An airplane is traveling at a constant speed of 200 m/s. Air enters the jet engine at the rate of 40 kg/s, while the combustion products are discharged at an exit velocity of 600 m/s relative to the airplane. The intake area is 0.3 square meters, and the exit area is 0.6 square meters. The ambient pressure is 0.7 atm, and the pressure at the exit of the engine 0.72 atm. Calculate the thrust developed by the engine. Assume uniform steady conditions at the inlet and exit and the properties of the products of combustion to be the same as those of air.
