Question

I need the solution step by step the correct solution is below

4.55 The total pressures, temperatures and mass flow rates at some stations inside a nonafterburning, mixed-flow turbofan engine, at takeoff, are shown. For simplicity of analysis, assume the gas is calorically perfect with constant properties (7-1-4 and 1004 Jkg K) throughout the engine. Calculate (a) bypass ratio, a (b) fuel-to-air ratio,f (c) mixer exit total temperature, T in K (d) exhaust Mach number, M (note that the exhaust nozzle is of convergent type) (e) (un-installed) takeoff thrust, Fo in kN and Ibf

Answer 1

This is the proper approach and solution for the given question.
