Darcy's law units
Darcy's law is an equation that describes the flow of a fluid through a porous medium. The law was formulated by Henry Darcy based on results of experiments on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences. It is analogous to Ohm's law in electrostatics, linearly relating the volume flow rate of the fluid to the hydraulic head difference (which is often just proportional to the pressure difference) via the hydraulic conductivity.

In 1856 the French engineer Henry P.G. Darcy presented his famous equation (Darcy, 1856) stating that flow rate ( q) depends on the pressure gradient (∇ H) and on the hydraulic conductivity ( K) (Eq. 1 ): (1)
WebFeb 2, 2024 · Darcy's law formula is one of the principles in hydrogeology describing water flow through a porous medium. According to Darcy's law equation, the amount of fluid flowing through a porous medium per unit of time is directly proportional to the hydraulic gradient, the cross-sectional area conducting the fluid, and the permeability of the material.
