- the state or quality of being permeable
- the measure of the ease with which a magnetic field can establish magnetic induction in a particular material
- the rate of diffusion of a fluid through a porous body
- the property of a porous substance, as rock or a membrane, of allowing the flow of a fluid through it
Permeability is how easily liquid and gas passes through something.
An example of permeability is how fast water flows through a porous rock.
- The property or condition of being permeable.
- The rate of flow of a liquid or gas through a porous material.
- 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.

- The first exact experiments demonstrating the changes which occur in the permeability of iron,, 3 Phil.
- In regard to water, all soils have two actions - namely, permeability and absorbability.
- So far, the best results have been attained with aluminium, and the permeability was greatest when the percentages of manganese and aluminium were approximately proportional to the atomic weights of the two metals.
- The practice of measuring magnetic induction and permeability with scientific accuracy was introduced in 1873 by H.
- The specimens distinguished by unusually high permeability were constituted as follows: Silicon-iron.
