A jet engine (straight jet engine) in cruise flight is given, see figure below. The speed of the air entering the engine is equal to the cruising speed V = 270 m/ s. The air around the engine has an atmospheric pressure of Patm = 26 kPa. A mass flow of fuel of 0.5 kg /s is added to the combustion chamber of the engine. Furthermore, there is given: Inlet: Outlet: A = 0.9 M Aput = 0.7 M pin = 0,41 kg/m pout = 0,28 kg/m Pressure p, - 26kPa Pressure pout 25kPa Vin= 270 m/s Vout Questions: a. Calculate the velocity Vout b. Calculate the Thrust (momentum equation)
