hydrostatic pressure


Hydrostatic pressure is the distributed force that a liquid exerts against the surfaces it is in contact with when it is at rest in a confined space. The hydrostatic properties of a liquid are nonuniform (variable) due to changes in the density of the fluid and the gravity within the container.

Example:

Fluid in a container exerts pressure on the walls of the container. The pressure of the fluid on the bottom of the container is greater than the pressure at the top due to the effect of gravity.

Hydrostatic pressure=ρgh

Where:

ρ=Fluid density

g=Acceleration of gravity

h=Height of fluid from bottom surface
