Question: The rocket in Fig P3.68 has a supersonic exhaust, and the exit pressure pe is not necessarily equal to pa. Show that the force F

The rocket in Fig P3.68 has a supersonic exhaust, and the exit pressure pe is not necessarily equal to pa. Show that the force F required to hold this rocket on the test stand is F = ρeAeVe 2 + Ae (pe − pa). Is this force F what we term the thrust of the rocket?
