Vena-contracta formed during flow of a liquid through an orificemeter has__________________?
Correct answer: B. Minimum liquid cross-section
- A. More diameter compared to orifice diameter
- B. Minimum liquid cross-section
- C. Minimum velocity of fluid stream
- D. None of these
Explanation
The vena contracta is the point where the jet has its smallest cross-sectional area after passing through the orifice, so its diameter is less than the orifice diameter and its velocity is highest.
