The Darcy Experiment (related to fluid flow)

The Darcy Experiment, conducted by Henry Darcy in 1856, studied how fluids flow through porous materials like sand or gravel. Darcy observed that the flow rate depends on the fluid’s viscosity, the pressure difference driving the flow, and the properties of the material such as permeability. He found that the flow is proportional to the pressure difference and inversely proportional to the fluid’s viscosity, leading to the Darcy Law. This principle helps engineers predict how water moves through groundwater basins, oil through rocks, or other fluids through porous structures in various applications.
