# Darcy Velocity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Darcy velocity, abbreviated as v, also called Darcy flux, is the volumetric flow per unit area of a porous mediun.

### Darcy Velocity or Flux Formula

$$\large{ v = k \; i }$$

Where:

$$\large{ v }$$ = Darcy velocity or flux

$$\large{ k }$$ = hydraulic conductivity

$$\large{ i }$$ = hydraulic gradient

Solve for:

$$\large{ k = \frac{v}{i} }$$

$$\large{ i = \frac{v}{k} }$$
