# What is Hydrostatics definition/concept

In nature, matter can be presented in three different ways, since something can be solid, liquid or gaseous. Each of these states is studied from a perspective. The branch of physics that studies liquid or gaseous states is called hydromechanics. Hydrostatics

In turn, this discipline has three branches: hydrostatics, hydrodynamics and pneumatics. The first studies liquids or fluids in equilibrium or at rest (this branch of physics is integrated into a more general area, fluid statics). Hydrodynamics studies liquids in motion and pneumatics is focused on the study of gases.

### Main rules of hydrostatics

Hydrostatic pressure is the force exerted by a liquid at rest and with a certain depth. Any fluid in a container exerts a certain amount of pressure in all directions. Hydrostatics

As for the concept of density , it refers to the amount of mass found in a given volume. On the other hand, specific weight measures the weight of each unit of volume. Thus, while density relates mass and volume, specific weight relates density and gravity.

The measurement of the weight of a fluid at rest is the hydrostatic pressure. Mathematically, this pressure is the result of multiplying the following variables: density, gravity, liquid and depth. The hydrostatic pressure unit is the pascal.

### There are two fundamental principles: Pascal and Archimedes

The principle of Pascal says that the pressure that occurs at any point of the mass of a fluid expands in the same way in all directions. Likewise, Pascal demonstrated that the pressure inside a container is not related to the amount of liquid, but to its height. Hydrostatics

Archimedes was a Greek scientist and engineer who lived in the III century; C. It is illustrious, among other reasons, for the principle that bears its name. Its principle is universally known: every body partially or totally submerged in a liquid has an upward buoyant force equal to the weight of the liquid in motion.

### Hydrostatic Applications

This branch of physics has a wide range of specific applications. We can highlight a few: any circumstance related to the underwater world, the design of dams and swamps, the extraction of water from underground wells and the measurements of liquids in deposits. Hydrostatics

If we take Pascal’s principle as a reference, the hydraulic press is the technology that best expresses your specific application.
