Kozeny-carman k-c equation

WebThe Kozeny–Carman equation describes the flow through granular soils and packed beds by estimating the permeability of the porous medium from the porosityεp and average particle diameter dp(see, for example, Ref. 5). Ergun WebThe results show that the K-C equation and the method for estimating the specific surface predict within an order of magnitude the saturated hydraulic conductivity of clayey to silty-sandy soils with measured hydraulic conductivity in the range 1 × 10 − 11 – 5 × 10 − 6 m/s.
