# Fluid Flow Pattern over Porous Medium Calculator

getcalc.com's **Darcy's Law Calculator** is an online mechanical engineering tool for fluid mechanics to estimate the flow patterns of fluid through porous medium (beds of sands), in both US customary & metric (SI) units.

## Definition & Formula

**Darcy's Law** is a describes the flow patterns of fluid through porous medium (beds of sands) to estimate the linear relationship between discharge flow velocity and hydraulic gradient of porous medium under steady laminar flow conditions.
