hydraulic conductivity
hydraulic conductivity[hī′drȯ·lik ‚kän‚dək′tiv·əd·ē] (fluid mechanics) permeability coefficient hydraulic conductivity
hy·drau·lic con·duc·tiv·i·tyease of pressure filtration of a liquid through a membrane; specifically, Kf = η(Q/A) (δx/δP), where Kf = hydraulic conductivity, η = viscosity of the liquid being filtered, Q/A = volume of liquid filtered per unit time and unit area, and δx/δP = 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/δP).See HC See KH |
