Hydrostatic pressure

The Hydrostatic Pressure calculator computes the pressure at the base of a column of fluid based on the height of the column (aka the head), the density of the fluid and the acceleration due to gravity.

INSTRUCTION: Choose units and enter the following:

• (ρ) This is the density of the fluid (e.g. water density is almost 1000 kg/m³)
• (g) This is the acceleration due to gravity (conventional, 9.80665 m/s2 to the sea surface)
• (h) This is the height of column of liquid

Hydrostatic Pressure (hp):  The calculator returns the pressure in pascals.  However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

Hydrostatic pressure is the pressure due to the weight of a fluid in a column such as a vertical pipe.

    hp=ρ•g•h

where:

• hp = hydrostatic pressure
• ρ =  density of the fluid (e.g. water density is approximately 1000 kg/m³)
• g = acceleration due to gravity (conventional, 9.80665 m/s2 to the sea surface)
• h = height of column of liquid
