Nozzle inlet state: identify pressure and velocity conditions at entry Select the correct combination for the state of steam at the <em>inlet</em> to a nozzle. Choose the correct option.

Difficulty: Easy

High pressure and a low velocity
High pressure and a high velocity
Low pressure and a low velocity
Low pressure and a high velocity

Correct Answer: High pressure and a low velocity

Explanation:

ConceptNozzles convert pressure energy into kinetic energy. Therefore, at the inlet the steam is at relatively high pressure and low velocity. Across the nozzle, pressure drops and velocity rises.

Final AnswerHigh pressure and a low velocity
