You have a constant area frictionless combustion chamber. at the entrance to the combustion chamber the mach number is 0.2 and the stagnation temperature is 675 k. the mach number is 0.47 at the exit to the combustion chamber.  = 1.4 and cp = 1 kj/kgk. a) what is the stagnation temperature at the exit of the combustion chamber? b) what is the ratio of the exit stagnation pressure to the entrance stagnation pressure? c) how high can the stagnation temperature rise in the combustion chamber before the flow reaches m = 1?
