WebThe fundamental law of fluid motion in porous media is Darcy’s Law. The mathematical expression developed in 1856 states that the velocity of a homogenous fluid in a porous medium is proportional to the pressure gradient and inversely proportional to the fluid viscosity (Tarek and McKinney [1]). Mathematically this can be expressed as: M L F ... WebAn enduring legacy of his work, Darcy's Law for flow in porous media, a cornerstone for several fields of study including groundwater hydrology, soil physics , and petroleum engineering remains widely used.
