Different Forms of The
Bernoulli Equation
In a Nutshell: The Bernoulli equation provides a
convenient way to relate changes of pressure, fluid
speed, and gravitational attraction for fluid acceleration in a flow
field. Understanding the limitations
of the Bernoulli equation is key to its correct application. The table below summarizes different forms
depending on the key limitations for each form. Click
here for definition of terms: inviscid, steady flow, irrotational
where P
= the pressure at the point of
the fluid particle along the streamline ρ = the mass density of the fluid particle V
= the speed of the fluid
particle g =
the acceleration of gravity z =
elevation of the fluid particle |
