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.

The 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, therefore, is calculated from with the following formula:

hydrostatic pressure

Along with hydrostatic pressure, there is also atmospheric pressure, which is the pressure exerted by the atmosphere on the fluid.

See also Pressure.

Hydrostatic pressure is the force that the fluid at rest exerts on the walls and obeys two principles:

Pascal’s principle

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

Archimedes’ principle

The principle of the Italian Archimedes (287 BC – 212 BC) describes the hydrostatic thrust that occurs 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 cleared when occupying the space bringing the object to buoyancy.
