PMF_darcylaw_kdarcy(): Hydraulic conductivity

About:

Calculate the hydraulic conductivity of a soil, based on the intrinsic conductivity in a porous media.

\begin{equation} K = \frac{k \times \gamma}{\mu} \end{equation}

Where,

$K$, hydraulic conductivity - $\frac{m}{s}$;

$k$, intrinsic permeability - $m^2$;

$\gamma$, fluid specific weight » WATER_density_gamma(), $\frac{N}{m^3}$;

$\mu$, dynamic viscosity » WATER_viscosity_dvisc(), $Pa \times s$.

Module: PorousMediaFlow

Function: PMF_darcylaw_kdarcy(t,s,k)

Parameters:

t , water temperature, oC;
s, water salinity, g/kg;
k, intrinsic permeability, m2.

Sample code:

from PorousMediaFlow import *

t = 10 #(.oC)
s = 2.5 #(g/kg)
k = 10**(-10) #(m2)

kdarcy = PMF_darcylaw_kdarcy(t,s,k)

print("K:",kdarcy,"m/s")

Result:

K: 0.0007559003751319023 m/s
