darcy to meter squared (m2) converter. Formula of darcy to meter squared (m2) , is 1 darcy is equivalent to 9.869E-13 meter squared (m2).To calculate just use formula 9.869E-13 meter squared (m2) * darcy.ormula of darcy to meter squared (m2) , is 1 darcy is equivalent to 9.869E-13 meter squared (m2).
The constant of proportionality K is called the hydraulic conductivity . The Darcy Velocity VD: VD = â K (âh/âL) and since Q = VD A ( where A = total area) Q = â KA (dh/dL) * Darcyâs Experiment 2. Head difference doesnât change with inclination of the sand filter 3.
