Pressure for downstream

—

Steady flow wey no compress and no get viscosity along one streamline; no pump, turbine or pipe loss. E no check cavitation.

Formula

P₂=P₁+½ρ(v₁²−v₂²)−ρg(h₂−h₁)

Estimate downstream pressure from changes in speed and elevation.

Where e fit work and limits

Steady flow wey no compress and no get viscosity along one streamline; no pump, turbine or pipe loss. E no check cavitation.

We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.

Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
