permeability

[ pur-mee-uh-bil-i-tee ]

/ ˌpɜr mi əˈbɪl ɪ ti /

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.

Origin of permeability

First recorded in 1750–60; perme(able) + -ability
