| hydrate | <chemistry> A compound formed by the union of water with some other substance, generally forming a neutral body, as certain crystallized salts. A substance which does not contain water as such, but has its constituents (hydrogen, oxygen, hydroxyl) so arranged that water may be eliminated; hence, a derivative of, or compound with, hydroxyl; hydroxide; as, ethyl hydrate, or common alcohol; calcium hydrate, or slaked lime. Origin: Gr. "ydwr water: cf. F. Hydrate. 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) |
