← ScienceWhich consequence results when a converging-diverging nozzle experiences choked flow?
A)Mass flow reaches its maximum✓
B)Exit pressure matches ambient pressure
C)Velocity becomes entirely subsonic
D)Temperature remains constant throughout nozzle
💡 Explanation
When the nozzle flow is choked the mass flow is maximized because the *flow velocity at the throat reaches the speed of sound*. Therefore, further reductions in downstream pressure do not increase mass flow, rather than affecting upstream conditions.
