Darcy's law
Darcy's law is the fundamental law of fluid motion in porous media published by Henry Darcy in 1856 [1].
Darcy's law has been successfully applied to determine the flow through permeable media since the early days of Petroleum Engineering.
Darcy's law History
Henry Darcy worked on the design of a filter large enough to process the Dijon towns daily water requirement [2].
By flowing water through the sand pack Darcy established that, for any flow rate, the velocity of the flow was directly proportional to the difference in manometric heights[2]:
Darcy's law Equation
