| hydraulic | Of or pertaining to hydraulics, or to fluids in motion; conveying, or acting by, water; as, an hydraulic clock, crane, or dock. Hydraulic accumulator, an accumulator for hydraulic machinery of any kind. See Accumulator. Hydraulic brake, a cataract. See Cataract. Hydraulic cement, a cement or mortar made of hydraulic lime, which will harden under water. Hydraulic elevator, a lift operated by the weight or pressure of water. Hydraulic jack. See Jack. Hydraulic lime, quicklime obtained from hydraulic limestone, and used for cementing under water, etc. Hydraulic limestone, a limestone which contains some clay, and which yields a quicklime that will set, or form a firm, strong mass, under water. Hydraulic main An inverted cup with a partition dipping into water, for opening or closing communication between two gas mains, the open ends of which protrude about the water. Origin: F. Hydraulique, L. Hydraulicus, fr. Gr, a water organ; "ydwr water + flute, pipe. See Hydra. Source: Websters Dictionary (01 Mar 1998) |

| hydraulic conductivity | Ease of pressure filtration of a liquid through a membrane; specifically, Kf = η(Q/A) (dx/dP), where Kf = hydraulic conductivity, η = viscosity of the liquid being filtered, Q/A = volume of liquid filtered per unit time and unit area, and dx/dP = reciprocal of the pressure gradient through the membrane; solute concentrations should be identical on both sides of the membrane. Also applied more loosely to measurements on a total membrane of unknown area and thickness with unmeasured fluid viscosity (K = Q/dP). (05 Mar 2000) |
| hydraulic load | Amount of liquid going into a system. (05 Dec 1998) |
| hydraulic motor | By altering the internal osmotic pressure within a cell, water will enter and a considerable expansion of the compartment will occur. This has been used as a motor device in plants (turgor pressure), in eversion of nematocysts and possibly in the production of other cellular protrusions. (18 Nov 1997) |
| hydraulics | That branch of science, or of engineering, which treats of fluids in motion, especially of water, its action in rivers and canals, the works and machinery for conducting or raising it, its use as a prime mover, and the like. As a science, hydraulics includes hydrodynamics, or the principles of mechanics applicable to the motion of water; as a branch of engineering, it consists in the practical application of the mechanics of fluids to the control and management of water with reference to the wants of man, including canals, waterworks, hydraulic machines, pumps, water wheels, etc. Some writers treat hydraulics and hydrostatics as subdivisions of hydrodynamics. Origin: Cf. F. Hydraulique. Source: Websters Dictionary (01 Mar 1998) |
