Question:medium

A convergent-divergent nozzle is used in jet engines to

Show Hint

For compressible flow, \[ \boxed{ \begin{aligned} \text{Convergent Nozzle} &\rightarrow M\le1 \text{Convergent-Divergent Nozzle} &\rightarrow M>1 \end{aligned} } \] Supersonic exhaust velocity produces higher thrust.
