Question: Air is expanded through a convergent-divergent nozzle from a large chamber in which the pressure and temperature are 200 kPa and 310 K, respectively. A normal shock wave occurs at a point in the nozzle where the Mach number is 2.5. The air is then brought to rest in a second large chamber. Find the pressure and temperature in this second chamber. Clearly state the assumptions you have made in arriving at the solution.
