Meaning of Hydrostatic Pressure

What is Hydrostatic Pressure:

In fluid mechanics, hydrostatic pressure is that which a fluid at rest generates by its own weight.

Hydrostatic pressure does not depend on the mass, weight or total volume of the fluid, but on the density of the fluid (p), the acceleration of gravity (g) and the depth of the fluid (h). The hydrostatic pressure is therefore calculated with the following formula:

Along with hydrostatic pressure, there is also atmospheric pressure, which is the pressure that the atmosphere exerts on the fluid.

See also Pressure.

Hydrostatic pressure is the force that the fluid in a state of rest exerts on the walls and obeys two principles:

Pascal’s principle

Pascal’s principle described by Blaise Pascal (1623-1662) notes that the pressure of static fluids is exerted in all directions such as, for example, the pressure that fluids exert on a fetus or in a airbag.

Archimedes’ principle

The principle of the Italian Archimedes (287 BC – 212 BC) describes the hydrostatic thrust that is produced when the pressure in a fluid increases with depth, that is, when an object is submerged in a fluid, it experiences an equivalent vertical and upward pressure to the fluid that was cleared by occupying the space, bringing the object to buoyancy.
