Darcy law of groundwater flow

WebApr 8, 2024 · Darcy's law is a conservation law that states the flow of a fluid through a pipe or other closed conduit is proportional to the transverse force acting on the fluid and inversely proportional to the viscosity of the fluid. It was introduced by the Scottish engineer Lord Kelvin in 1890. WebNov 23, 2024 · The multiphase flow equation is referred to as Darcy’s law. There are many articles about multiphase flow in the oil and gas industry. One of them is called “Darcy’s Law for Multiphase Flow. Limitation of Darcy’s Law .
