Explanation:
Coefficient Of Velocity. The proportion of real speed of the stream, at vena-contract a, to the hypothetical speed is known as the coefficient of speed. Write the equation for coefficient of velocity. Here, actual velocity is vact, theoretical velocity is vth, gravity is g, and height is h...

Consider an orifice is fitted with a tank. The liquid particles, in order to flow out through the orifice, move towards the orifice from all directions. A few of the particles first move downward, then take a turn to enter into the orifice and then finally flow through it.
It may be noted, that the liquid particles loose some energy, while taking the turn to enter into the orifice. It can be observed that the jet, after leaving the orifice, gets contracted. The maximum contraction takes place at a section slightly on the downstream side of the orifice, where the jet is more or less horizontal. Such a section is known as Vena-Contracta.
HOPE ITS HELPFUL.
