Answer 2

Answer:

The critical pressure ratio for initially wet steam is 0.582.

Option C

Explanation:

The critical pressure ratio helps to determine the speed of the fluid that is going to pass through a very thin nozzle. This critical pressure ratio is defined as the pressure where the flow of liquid is accelerated to such an extent that it corresponds with speed of sound through that fluid. This determines the pressure required to push that fluid through the nozzle. And, it is also dependent on the elasticity and compressibility of the fluid.
