permeability

(ˌpɜːmɪəˈbɪlɪtɪ)
n
1. the state or quality of being permeable
2. (General Physics) a measure of the response of a medium to a magnetic field, expressed as the ratio of the magnetic flux density in the medium to the field strength; measured in henries per metre. Symbol: μ See also relative permeability, magnetic constant
3. (Civil Engineering) civil engineering the rate of diffusion of a fluid under pressure through soil
4. (Aeronautics) the rate at which gas diffuses through the surface of a balloon or airship, usually expressed in litres per square metre per day
