-
AHigh pressure and a low velocity
-
BHigh pressure and a high velocity
-
CLow pressure and a low velocity
-
DLow pressure and a high velocity
Answer
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
