13. A small aircraft is powered by a turbojet engine and travels at 200 m/s. The intake can be assumed to be circular, with a diameter of 1.8 m. At cruising altitude p = 0.7 bar, R-287J/kgK and T = 240 K. Assume the engine to behave as a control volume and air to behave as an ideal gas a) Calculate is the required air speed relative to the engines to produce a thrust of 100 KN. [10 marks] b) Sketch a T-S diagram for a Joule-Brayton cycle. Label all salient points. (5 marks] c) Describe, with an appropriate sketch, the purpose of an inter-cooler in a gas turbine cycle. [10 marks]
