hydrostatic pressure
hydrostatic pressuren. The pressure exerted by gravity at a given point within a fluid that is at equilibrium, increasing in proportion to depth from the surface.hydrostatic pressure
hydrostatic pressure[‚hī·drə′stad·ik ′presh·ər] (fluid mechanics) The pressure at a point in a fluid at rest due to the weight of the fluid above it. Also known as gravitational pressure. The negative of the stress normal to a surface in a fluid. hydrostatic pressureThe pressure equivalent to that exerted on a surface by a column of water of a given height.hydrostatic pressure
hy·dro·stat·ic pres·surethe pressure exerted by a liquid as a result of its potential energy, ignoring its kinetic energy; frequently used to distinguish a true pressure from an osmotic pressure or to emphasize the variation in pressure in a column of fluid due to the effect of gravity.hydrostatic pressureThe pressure exerted by a fluid within a closed system.See also: pressure |
