BSpecific volume of steam
-
CDryness fraction of steam
-
DAll of these
Answer
Correct Answer: All of these
Explanation
Concept/Approach
- Nozzle flow couples momentum and state: velocity rise drives static pressure drop (Bernoulli/energy balance).
- Steam's specific volume (compressibility) and dryness fraction (quality) affect density and hence acceleration and pressure–area relations.
