permeability [‚pər·mē·ə′bil·əd·ē]
(electromagnetism)
A factor, characteristic of a material, that is proportional to the magnetic induction produced in a material divided by the magnetic field strength; it is a tensor when these quantities are not parallel. Also known as magnetic permeability.
(fluid mechanics)
The ability of a membrane or other material to permit a substance to pass through it.
Quantitatively, the amount of substance which passes through the material under given conditions.
(geology)
The capacity of a porous rock, soil, or sediment for transmitting a fluid without damage to the structure of the medium. Also known as conductivity; perviousness.
(naval architecture)
The percentage of a given space in a ship that can be occupied by water.
permeability
