Air as an ideal gas with k51.4 enters a converging–diverging duct with a mach number of 2. at the inlet, the pressure is 26 lbf/in.2 and the temperature is 4458r. a normal shock stands at a location in the converging section of the duct, with mx5 1.5. at the exit of the duct, the pressure is 150 lbf/in.2 the flow is isentropic everywhere except in the immediate vicinity of the shock. determine temperature, in 8r, and the mach number at the exit
