WebDarcy’s law (Equation 1) states that the volumetric flow rate, Q, is proportional to: (1) the difference in hydraulic head along a length interval, Δ L; (2) a coefficient K (hydraulic conductivity), which accounts for restriction to flow imposed by the solid medium and for the density and viscosity of the fluid flowing through the porous medium … WebJan 16, 2016 · Darcy’s law is based on the experimental observation that the apparent fluid velocity is proportional to the applied pressure gradient on a porous medium. This observation is analogous to the flow of fluid through pipes and capillaries (Poisseuille’s law) and also to that of the flow of current through a resistive conductor.
