Torricelli's Law

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

torricellis law 1Torricelli's law, also called Torricelli's principle or Torricelli's theorem, is the fluid efflux velocity flowing through an orifice under gravity at the bottom of a tank filled to a depth.  This is the same velocity from the orifice as a falling body over the same height due to gravity.


Torricelli's law formula

\(\large{ v = \sqrt{ 2 \; g \; h  }  }\)   


\(\large{ v }\) = velocity

\(\large{ h }\)  (Greek symbol rho) = height

\(\large{ g }\) = gravitational acceleration
