For the flow of an ideal, incompressible, non-viscous fluid, the Bernoulli’s equation, can be expressed as:
(Notations: p - intensity of pressure, γ - unit weight of fluid, v - velocity of flow, Z - datum head, g - acceleration due to gravity).
1
\(\rm Z - \frac{p}{\gamma} + \frac{v^2}{2g} = Const\)
2
\(\rm Z + \frac{p}{\gamma} + \frac{v^2}{g} = Const\)
3
\(\rm Z + \frac{p}{\gamma} + \frac{v^2}{2g} = Const\)
4
\(\rm Z - \frac{p}{\gamma} + \frac{v^2}{g} = Const\)
