Darcy's Law

Darcy's Law describes how fluids flow through porous materials, like water through soil. It states that the flow rate of the fluid is directly proportional to the pressure difference across the material and inversely proportional to its resistance to flow. In simpler terms, if you have a bucket of water and poke a hole in the bottom, the speed at which water flows out depends on how high the water level is (pressure) and how easily it can pass through the hole (resistance). This principle is essential in fields like hydrology, civil engineering, and petroleum engineering.
