WebPermeability is defined in units of area, which relates to the area of open pore space in the cross section that faces, or is perpendicular to, the direc- tion of flowing fluid. In the … Permeability is a property of porous materials that is an indication of the ability for fluids (gas or liquid) to flow through them. Fluids can more easily flow through a material with high permeability than one with low permeability. The permeability of a medium is related to the porosity, but also to the shapes of the … Zobraziť viac The SI unit for permeability is m2.

The darcy (or darcy unit) and millidarcy (md or mD) are units of permeability, named after Henry Darcy. They are not SI units, but they are widely used in petroleum engineering and geology. The unit has also been used in biophysics and biomechanics, where the flow of fluids such as blood through capillary beds and cerebrospinal fluid through the brain interstitial space is being examined. A darcy has dimensional units of length . Webk 20 = a k t = (0.8971)(0.0008465 cm/s) = 0.007594 cm/s. Definitions.
