For supersonic jet, C – D nozzle is used for the acceleration of exhaust.

For supersonic jet, C – D nozzle is used for the acceleration of exhaust. Correct Answer True

A Typical C – D nozzle consists of convergent section as well as divergent section. Apart from those it also includes a throat section at where flow is in sonic condition. Incoming flow initially has subsonic speed which is increased by convergent section. At throat, flow reaches the sonic speed and as it progresses further in the divergent section it further expands to supersonic speeds.
