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

The actual velocity at vena contracta for flow through an orifice from a reservoir of height H Correct Answer <span class="math-tex">\({C_v}\sqrt {2gH} \)</span>

Explanation:

Orifice meter

Additional Information

Coefficient of discharge (Cd) of orifice meter is the ratio of actual discharge to theoretical discharge through orifice meter.                        

Cd of orifice meter lies between 0.65 to 0.68.

Coefficient of contraction (Cc)  is defined as the ratio of the area of cross-section of vena contracta to the area of cross-section of the orifice.

Relation among Cd, Cc, and Cv:

Cd = Cc × Cv
