Hydrostatic Pressure vs. Depth

Calculate hydrostatic pressure in a liquid based on depth using the formula p = ρ g h, where ρ is density, g is acceleration of gravity, and h is the height of fluid column or depth.

Hydrostatic Pressure vs. Depth

Hydrostatic pressure in a liquid can be calculated as:

p = ρ g h

Where:

p = pressure in liquid (N/m², Pa, lbf/ft², psf)
ρ = density of liquid (kg/m³, slugs/ft³)
g = acceleration of gravity (9.81 m/s², 32.17405 ft/s²)
h = height of fluid column or depth in the fluid where pressure is measured (m, ft)

For water at 4°C with a density of 1000 kg/m³, the hydrostatic pressure increases linearly with depth.
