Question: A jet engine is running on a test bed. The stagnation pressure and stagnation temperature just upstream of the convergent nozzle fitted to the rear of this engine are found to be 700 kPa and 700°C, respectively. The exit diameter of the nozzle is 0.5 m. If the test is being run at an ambient pressure of 101 kPa, find the mass flow rate through the engine, the jet exit velocity and the thrust that is developed by the engine. Assume the gases have the properties of air.
