Hydrostatic refers to the study of fluids at rest. It is a branch of fluid mechanics that deals with the properties and behavior of liquids and gases that are not in motion. Key principles in hydrostatics include pressure, buoyancy, and Pascal's principle.

Pressure in a fluid at rest is defined as the force exerted per unit area. This pressure increases with depth due to the weight of the fluid above. Hydrostatic pressure acts equally in all directions at a given point within the fluid.

Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. Archimedes' principle states that this buoyant force is equal to the weight of the fluid displaced by the object. If the buoyant force is greater than the object's weight, the object will float.

Pascal's principle, also known as the Pascal-Blaise law, states that a change in pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. This principle is the basis for many hydraulic systems, such as hydraulic jacks and brakes.

Hydrostatic principles are applied in various fields, including civil engineering for the design of dams and reservoirs, naval architecture for the design of ships, and in medical applications like tonometry to measure intraocular pressure. Understanding hydrostatic forces is crucial for predicting the behavior of fluids in static conditions.
