Question

The actual velocity at vena contracta for flow through an orifice from a reservoir of height H =

• A. $$\sqrt{2gH}$$
• B. $$C_{v} \sqrt{2gH}$$
• C. $$\frac{ \sqrt{2gH}}{C_v}$$
• D. $$C_{d} \sqrt{2gH}$$

Answer 1

Answer:

$$C_{v} \sqrt{2gH}$$

The velocity at vena contracta for flow through an orifice from a reservoir of height H is given by

$V = C_{v} \sqrt{2gH}$
