## Frequently Asked Questions

To calculate the flow rate using Darcy's law, you first need to find out the hydraulic conductivity and hydraulic gradient for the given porous medium. After that, put those values in the Q = -KA(dh/dl) equation to perform Darcy's law calculation.

Darcy's formula or Darcy's law is used to describe the flow of fluids through porous media, such as soil, sand, and rock.

Darcy's law is a fundamental principle in the field of fluid mechanics and is widely used to model fluid flow through porous media. However, its validity is limited to certain conditions and assumptions like e fluid is incompressible and has constant density, flow is steady-state and laminar, with no turbulence, the fluid and porous medium are in thermal equilibrium, etc.

Darcy's law is discovered by Henry Darcy. He was a French engineer who first described Darcy's law in the mid-19th century. Darcy conducted experiments to investigate the flow of water through sand filters, which were commonly used to purify drinking water at the time.
