A stream of air behaving as a perfect gas with a velocity of
500(m)/(s), a static temperature of
-23\deg Cand a density of
1.412k(g)/(m^(3))undergoes a normal shock wave in a nozzle. If the ratio of specific heats is equal to 1.4 and the gas constant has a value of
0.287k(J)/(k)gKdetermine:- (i) the stagnation pressure before the wave (ii) the stagnation temperature before the wave (iii) the Mach number after the wave (iv) the velocity after the wave ( 3 marks) (2 marks) ( 2 marks) ( 3 marks) (v) the change in specific entropy across the shock wave. (4 marks)
