DARCY’S LAW

Darcy’s law: translation

An empirical law given as which states that the average volumetric discharge of flow through a porous medium is directly proportional to the hydraulic gradient assuming that the flow is laminar and inertia can be neglected.

Note:Q=discharge,K=hydraulic conductivity,A=cross-sectional area,dh/dL=gradient, and a minus sign is attached as a convention to indicate that flow occurs in the direction of decreasing head [5].
