Question

1.Explain coefficient of permeability using Darcy's law​

Answer 1

Darcy's law, as refined by Morris Muskat, in the absence of gravitational forces and in a homogeneously permeable medium, is given by a simple proportionality relationship between the instantaneous flux (q = Q/A, unit: (m3 of fluid/s) / m2) through a porous medium, the permeability of the medium, the dynamic viscosity ...

Answer 2

Answer:

Darcy’s law describes the relationship among the instantaneous rate of discharge through porous medium and pressure drop at a distance.

Darcy's permeability is a property of both the porous medium and the fluid moving through the porous medium. In fact, Darcy's law is the empirical equivalent of the Navier-Stokes equations. ... While this relationship is broadly correct, this indicates that the permeability k is directly proportional to gravity.
