Meaning of Hydrostatic

What is Hydrostatic:

The hydrostatic is the study of fluids at rest which belongs to the field of fluid mechanics, also called hydraulics.

See also Hydraulics.

The principle of hydrostatics indicates that the pressure difference between two points of the same liquid is equal to the product of the specific weight of the liquid determined by the difference in levels. This principle is expressed in the following formula:

hydrostatic

In thermodynamic physics, hydrostatic pressure is that which the same fluid at rest exerts on its weight. In hydrostatics or the study of fluids at rest, there is hydrostatic pressure and atmospheric pressure, the latter being the pressure exerted by the atmosphere on the fluid.

The solid, liquid and gaseous states behave under the same laws, but fluids have a special ability to change shape, increasing their volume and not their mass.

In this way, the hydrostatics is measured through the density (p), gravity (g) and depth (h) of the fluid, and not by its mass or volume. Hydrostatic pressure is defined by the following formula:

hydrostatic pressure

To calculate the hydrostatic and its pressure, two principles must also be taken that define its behavior:

  • pascal’s principle which indicates that a liquid at rest exerts pressure in all directions, and
  • Archimedes’ principle describes how the increase in depth causes greater pressure allowing the buoyancy of objects within the liquid.

On the other hand, hydrodynamics is the science that studies fluids in motion.

hydrostatic pressure

Hydrostatic pressure is that exerted by a fluid at rest on itself due to its own weight. It is defined as the product between the density of the fluid, the acceleration of gravity and the depth in which the fluid is found.
