Calculation
p₁ + ½ρv₁² + ρgz₁ = p₂ + ½ρv₂² + ρgz₂
Pressure can convert to velocity or elevation; friction and pump heads must be added separately.

Result
Select a target and calculate.
Understand the inputs
- Pressure at point 2 p₂ — Unknown static pressure at point 2.
- Pressure at point 1 p₁ — Static pressure at point 1.
- Density ρ — Density of incompressible fluid.
- Velocity v₁ — Mean velocity at point 1.
- Velocity v₂ — Mean velocity at point 2.
- Elevation z₁ — Elevation of point 1 above datum.
- Elevation z₂ — Elevation of point 2 above datum.
Example
A higher outlet or faster outlet lowers ideal static pressure.
Assumptions and limits
Steady, incompressible, frictionless; no pump between points.
