Q5: A converging-diverging nozzle, which is shown in the figure, is supplied with air from a large tank where the pressure is Po and exhausts to the atmosphere with a pressure of Ph. The area A at distance x from the throat is given by (A = At (1 + 0.75x/L)), where At is the throat cross- sectional area and Lis the total length of the diverging part of the nozzle. At a certain pressure ratio P/P, a normal shock wave stands in the nozzle at a point where the Mach number before the shock is 1.7. Find the position of the normal shock wave from the throat, and the pressure ratio P/Po. Ans.: 0.45 L = 0.753 P.
