1. A diffuser is a divergent nozzle used to reduce a flow velocity. Is there a limit for the Mach number for it to work this way?
2. Sketch the variation in V, T, P, ρ, and M for a subsonic flow into a convergent nozzle with M = 1 at the exit plane.
3. Sketch the variation in V, T, P, ρ, and M for a sonic (M = 1) flow into a divergent nozzle with M = 2 at the exit plane.
