- A Plane Flying At 300 M S Airspeed Uses A Turbojet Engine To Provide Thrust At Its Operational Altitude The Air Has A 1 (30.53 KiB) Viewed 39 times
A plane flying at 300 m/s airspeed uses a turbojet engine to provide thrust. At its operational altitude, the air has a pressure of 37 kPa and a temperature of -7 °C. The fuel-air ratio is 0.6% - that is, for every kg of air passing through the turbine, 0.006 kg of fuel is burned - and the jet fuel used has a heating value of 44 MJ/kg. If the compressor pressure ratio is 13, and we assume that flow speed is negligibly small between the compressor inlet and turbine outlet, determine the temperature of the exhaust gases to the nearest Kelvin. Use the same properties for air as in question 10 and treat all components as ideal.
