Torricelli theorem

Not to be confused with Torricelli's Equation.

Torricelli's theorem is a theorem named after Evangelista Torricelli with applications in chemistry and mechanic of fluids.

Statement

"The speed of efflux is equal to the velocity gained by the distance (h-hi) under the action of gravity"

$v_{i}={\sqrt {2g(h-h_{i})}}$

Where:

$v_{i}$ = Speed of Efflux from the hole(i)

$g$ = Gravitational Acceleration Constant

$h$ = Height of fluid in the Vessil

$h_{i}$ = Height of efflux point from the base
