Hydrostatic Pressure Water

Reference data and engineering information about hydrostatic pressure water for fluid mechanics applications.

hydrostaticpressurewaterCalculator

Overview

Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid column above. It increases linearly with depth and is independent of container shape.

Variables

Symbol	Description	Unit
$P$	Hydrostatic pressure	Pa
$\rho$	Fluid density	kg/m³
$g$	Gravitational acceleration	m/s²
$h$	Depth below surface	m

Formula

$P = \rho g h$
