PMF_darcylaw_v(): flux velocity in porous media

About:

Calculate the flux velocity in porous media according to the Darcy law.

\begin{equation} V = \frac{q}{n} \end{equation}

Where,

$q$, specific discharge » PMF_darcylaw_q() - $\frac{m}{s}$;

$n$, media porosity, $0...1$.

Module: PorousMediaFlow

Function: PMF_darcylaw_v(dh,dx,t,s,k,n)

Parameters:

dh, variation of water level, oC;
dx, distance between water levels, g/kg;
t , water temperature, oC;
s, water salinity, g/kg;
k, intrinsic permeability, m2;
n, media porosity,0...1.

Sample code:

from PorousMediaFlow import *

dh = -0.1 # (m)
dx = 100 # (m)
t = 10 #(.oC)
s = 2.5 #g/kg
k = 10**(-10) #(m2)
n = 0.35

v = PMF_darcylaw_v(dh,dx,t,s,k,n)

print("V:",v,"m/s")

Result:

V: 0.001661911549637972 m/s
