Hydrostatic

Hydrostatic (pronunciation: /ˌhaɪdrəˈstatɪk/) is a term derived from the Greek words 'hydro' meaning water and 'static' meaning stationary. It refers to the study of fluids at rest and the pressure in a fluid or exerted by a fluid on an immersed body.

Definition

In Physics, hydrostatics is a sub-discipline of Fluid Mechanics that specifically deals with fluids at rest. It encompasses the study of the conditions under which fluids are at rest in stable equilibrium and is contrasted with Hydrodynamics, the study of fluids in motion.

Hydrostatic Pressure

Hydrostatic Pressure is the pressure exerted by a fluid at equilibrium due to the force of gravity. It increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.

Hydrostatic Equilibrium

Hydrostatic Equilibrium is the state of a fluid in which all points experience the same pressure, except for the variations in pressure caused by gravity. This state is particularly relevant in Astronomy and Astrophysics, where it describes the balance between the gravitational force and the outward pressure force in celestial bodies.

Hydrostatic Test

A Hydrostatic Test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers, and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, and pressurization of the vessel to the specified test pressure.
