A
Darcy's Law applies to non-compressible fluids
passing through a porous medium if the seepage is
sufficiently slow that inertia and Turbulence
are insignificant. It describes a One form: κAΔp Q = - ———— μL - Q - Darcy Velocity, volume per unit time.
- κ - permeability of the medium.
- A - cross-sectional area of the medium.
- Δp - difference in pressure.
- μ - viscosity of the fluid.
- L - length of the medium.
Navier-Stokes Equations are more general, and Darcy's Law can be derived from them. hydrology,fluid dynamics,field) |
