Discuss the below:
Q: Air, supplied by a reservoir at 450 kPa, flows through a converging-diverging nozzle whose throat area is 12 cm2. A normal shock stands where A1 = 20 cm2.
(a) Compute the pressure just downstream of this shock. Still farther downstream, where A3 = 30 cm2, estimate
(b) P3;
(c) A3; and
(d) Ma3.
