8.3.- HYDROSTATICS

Hydrostatics is the branch of fluid mechanics that studies the associated phenomena and behavior that occur when a fluid is in a container and there are no forces that modify the state of the liquid at rest or in motion. By contrast, hydrodynamics studies fluids in motion.

Hydrostatics is based on Pascal’s principle and Archimedes’ principle. Pascal’s principle states that "in a fluid confined in a container, pressure is transmitted in all directions with equal intensity". Likewise, Archimedes' principle states that when a body is submerged in a fluid, it exerts an upward force on the body equal to the weight of the fluid displaced by it",. The fundamental equation of hydrostatics is defined from these principles:

dP = ρ g dh

Where,

P: pressure at one point of the fluid

ρ: density of the fluid

g: gravitational acceleration of Earth

h: height

The equation explains that within a fluid the hydrostatic pressure is directly proportional to its density, to the depth and the gravity of the fluid at the reference point considered.

The following characteristics that describe liquids stand out in hydrostatics: cohesion forces, surface tension, adhesion and capillarity. These characteristics are considered for applications based on hydrostatic studies such as: brakes, presses and hydraulic elevators, in the dimensioning of structures as canals and spillways, in shipbuilding, etc.
