For flow through an orifice from a reservoir, the actual velocity at the vena contracta is given by _________________?
Correct answer: B. C.V. √(2gh)
- A. √(2gh)
- B. C.V. √(2gh)
- C. Cd √(2gh)
- D. Cc √(2gh)
Explanation
The ideal velocity from the reservoir head is √(2gh), while the actual velocity is reduced by the coefficient of velocity, Cv. Therefore, velocity at the vena contracta is Cv√(2gh).
