A diver experiences hydrostatic pressure at depth.

Definition

1. Adjective:
   • Relating to fluids at rest: Describing the branch of fluid mechanics that deals with liquids and gases that are not in motion.
   • Concerning the pressure exerted by a stationary fluid: Pertaining to the pressure a fluid exerts due to its weight when it is not flowing.

Usage Examples

• Adjective:
  • The engineer calculated the hydrostatic pressure at the bottom of the reservoir.
  • A hydrostatic test is performed to check for leaks in pipelines by filling them with water.
  • The principles of hydrostatic equilibrium explain why atmospheric pressure decreases with altitude.

Advanced Usage

• "Hydrostatic equilibrium": A state in fluid mechanics where the force of gravity is balanced by a pressure gradient force, preventing the fluid from collapsing or expanding.
  • Stars maintain their shape through hydrostatic equilibrium.
• "Hydrostatic skeleton": A structure found in some invertebrates where fluid pressure within body compartments provides support and enables movement.
  • An earthworm uses its hydrostatic skeleton to burrow through soil.

Variants and Related Words

• Hydrostatics (n): The branch of fluid mechanics concerned with fluids at rest.
  • The study of hydrostatics involves understanding pressure in stationary liquids.
• Hydrostatically (adv): In a manner relating to hydrostatics.
  • The tank was tested hydrostatically.

Synonyms

• Fluid-static: Pertaining to stationary fluids (a more technical synonym).
• Static-fluid: Relating to fluids not in motion.

Related Phrases and Compounds

• Hydrostatic pressure: The pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity.
  • Submarines must be designed to withstand immense hydrostatic pressure at depth.
• Hydrostatic head: The vertical height of a fluid column, which determines the pressure at its base.
  • The hydrostatic head of water behind the dam creates the potential energy for hydroelectric power.
