Vena-contracta pressure tapping is at a distance _______________ from the position of an orificemeter fitted in a pipe of internal diameter 'd' ?
Correct answer: B. 0.5 d
- A. d
- B. 0.5 d
- C. 2d
- D. 4d
Explanation
For a standard orifice meter, the vena contracta is located approximately 0.5 pipe diameters downstream of the orifice plate. Pressure tapping at this location measures the minimum-pressure region used in the flow calculation.
