darcys law 3Hydraulic conductivity, abbreviated as k, is the ease with which a fluid can move through porous spaces or fractures.  

 

Hydraulic Conductivity formulas

\(\large{ k = \frac{ Q }{ i \; A_c }   }\)   
\(\large{ k =  \frac{v}{i}   }\)   (Darcy velocity
\(\large{ k =  \frac{ K \; \rho_w \; g  }{ \mu_w }   }\)   

Where:

\(\large{ k }\) = hydraulic conductivity

\(\large{ A_c }\) = area cross-section of flow

\(\large{ v }\) = Darcy velocity or flux

\(\large{ Q }\) = flow rate

\(\large{ i }\) = hydraulic gradient

\(\large{ K }\) = permeability coefficient

\(\large{ \rho_w }\)  (Greek symbol rho) = density of pure water

\(\large{ g }\) = standard gravity

\(\large{ \mu_w }\)  (Greek symbol mu) = dynamic viscosity of water
