The vena contracta is the point of minimum cross- sectional area and maximum velocity in a fluid jet after exiting an orifice or nozzle. The actual velocity at the vena contracta is less than the theoretical velocity due to energy losses, and it is accounted for by the coefficient of velocity ($C_v$).
At the vena contracta, the velocity of flow is given by - $\sqrt{2gh}$ - $\sqrt{2g}$ - $\sqrt{2g} \times h$ - $C_v \times \sqrt{2gh}$ - Question not attempted
