Q.5 A supersonic wind tunnel, which is shown in the figure, is fed from a large tank.
The air is discharged to the atmosphere. The Mach number in the test section is 2.65
and a normal shock wave stands at the exit of the wind tunnel. The pressure at section
3 immediately after the normal shock wave is 100 kPa. The flow is isentropic except
through the normal shock wave. Find:
1. Po, P1, P2 and M3.
2. If a Pitot tube is placed in the exit jet, then calculate the pressure measured by the
Pitot tube.
