A converging-diverging nozzle with an exit-to-sonic area ratio of A/A = 47, exhausts air from a high-pressure reservoir (T, = 270 K) to the back plane, where the pressure is fixed at p, = 1 atm [abs]. The test section area is A = 0.06 m? and the reservoir has a volume of 50 m. a) Assume that the test is located immediately upstream of the exit and that the flow up to the exit is isentropic, what is the minimum stagnation pressure under which the tunnel will start?
