Coefficient of permeability definition
Coefficient of permeability and "Hydraulic Conductivity" shall mean the rate of laminar flow of water through a unit cross-sectional area of a porous medium under a unit hydraulic gradient at a standard temperature. The units of "Coefficient of Permeability" and "Hydraulic Conductivity" shall be expressed in centimeters per second.
Examples of Coefficient of permeability in a sentence
Where drainage drywells are proposed as stormwater infiltration infrastructure, the required drainage drywell wall surface areas shall be determined using Darcy's Empirical Law as follows: Where: Q = Design flow in m3/s; A = Cross-sectional area of soil through which flow takes place in m2; K = Coefficient of permeability of receiving soils in m/s; i = Hydraulic gradient within proximity to the drywell.
