# Venturimeter is a device based on

A venturi meter is a device which is based on the principle of Bernoulli’s equation.

Bernoulli’s equation states that the total energy of an incompressible fluid in a steady-state must be equal to constant. Pressure energy, potential energy, and kinetic energy make up the total energy.

Pressure energy + Kinetic energy + Potential energy = Constant

$\frac{p}{\rho g}+\frac{v^{2}}{2g}+z=constant$
