permeability
[pur-mee-uh-bil-i-tee]
noun
the property or state of being permeable.
Also called magnetic permeability.Electricity.a measure of the change in magnetic induction produced when a magnetic material replaces air, expressed as a coefficient or a set of coefficients that multiply the components of magnetic intensity to give the components of magnetic induction.
Geology.the capability of a porous rock or sediment to permit the flow of fluids through its pore spaces.
Aeronautics.the rate at which gas is lost through the envelope of an aerostat, usually expressed as the number of liters thus diffused in one day through a square meter.
Nautical.the capacity of a space in a vessel to absorb water, measured with reference to its temporary or permanent contents and expressed as a percentage of the total volume of the space.

permeability
The ability of a substance to allow another substance to pass through it, especially the ability of a porous rock, sediment, or soil to transmit fluid through pores and cracks. Geologic permeability is usually measured in millidarcies.

When To Use
Permeability is the quality or state of being permeable—able to be penetrated or passed through, especially by a liquid or gas.The verb permeate means to penetrate, pass through, and often become widespread throughout something. Similar words are pervade and saturate.Permeate can be used both in the context of the physical spread of something within a space and in more figurative ways. Water permeates the soil. Dye permeates fabric. An idea can permeate someone’s mind. In these cases, the fabric and the mind could be described as permeable.Things that are permeable have different levels of permeability. For example, certain materials may easily absorb liquid, while others may only allow small amounts of liquid to permeate their surface.The word permeability is used in several more specific ways in the context of ships, aircraft, electricity, and geology.Example: This type of stone was chosen for its permeability—it absorbs water.
