Which of the following statement is wrong?

Options:

A . The critical pressure gives the velocity of steam at the throat equal to the velocity of sound.

B . The flowin the convergent portion of the nozzle is sub-sonic.

C . The flow in the divergent portion of the nozzle is super-sonic.

D . To increase the velocity of steam above sonic velocity (super-sonic) by expanding steam below the critical pressure, the divergent portion for the nozzle is not necessary.

Answer: Option D
Answer: (d).To increase the velocity of steam above sonic velocity (super-sonic) by expanding steam below the critical pressure, the divergent portion for the nozzle is not necessary.
