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. [1] The permeability of a medium is related to the porosity, but also to the shapes of the pores in the medium and their level of connectedness.
