Quizplus · Accepted Answer

In a convergent-divergent nozzle, the flow of steam becomes supersonic in the divergent portion of the nozzle. This occurs after the steam passes through the throat, where it reaches the speed of sound (Mach 1), and then accelerates to supersonic speeds in the divergent section.
