Joukowsky Equation for Fluids

The Joukowsky equation measures the change in pressure of a fluid resulting from a change in the fluid’s velocity and is written as:

(1)

where = change in pressure, = density, c = fluid wave speed (speed of sound), = change in velocity.

This equation is used most widely for calculating the maximum theoretical surge pressure or head resulting from instantenous valve closure in a piping or pipeline system.
