Webpermeability. 1. n. [Geology] The ability, or measurement of a rock 's ability, to transmit fluids, typically measured in darcies or millidarcies. The term was basically defined by Henry Darcy, who showed that the common mathematics of heat transfer could be modified to adequately describe fluid flow in porous media. Web8. jan 2024 · Coupling gas permeability (Kg) with Poiseuille law is able to evaluate a “mean” crack initial width. Water permeability was mainly recorded to be compared to the water permeability of “intact” COx argillite.

WebPermeability is related to particle size distribution. Permeability Cake Density (PCD) The wet cake density is also measured by the permeability method (S.T.M. Nr. I-9). This value gives the wet cake density in lbs/ft³ (x16 » kg/m³). Perlite filteraids form lower density cakes than diatomite filteraids of comparable permeabilities.
