Q.4 A converging-diverging nozzle, which is shown in the figure, is supplied with air from a large tank where the pressure is P, and exhausts to the atmosphere with a pressure of Ph. The area A at distance x from the throat is given by (A=A, (1+0.75x/L), where A, is the throat cross-sectional area and L is the total length of the diverging part of the nozzle. At a certain pressure ratio P/Pp, 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.

Transcribed Image Text:Q.4 A converging-diverging nozzle, which is shown in the figure, is supplied with
air from a large tank where the pressure is P, and exhausts to the atmosphere with a
pressure of P. The area A at distance x from the throat is given by (A=A,
(1+0.75x/L), where A, is the throat cross-sectional area and L is the total length of
the diverging part of the nozzle. At a certain pressure ratio P/Pb, 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
