 (pûr′mē-ə-bĭl′ĭ-tē)
n. pl. per·me·a·bil·i·ties

2. The rate of flow of a liquid or gas through a porous material.

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

Analogously to electrical resistances combined in series, the overall permeability can be written as a combination of the permeabilities of the support and of the paint film:
Many semicrystalline polymers also have lower permeabilities than PIB (e.
Soil permeabilities determined with water as the infiltrating fluid can also be affected by the presence of encapsulated air in dry soils.
The versatility of the L100-5000 tester also extends to measuring a wide range of high and low permeabilities and can thus be used to test a variety of products including packaging films for food and tobacco, material for contact lenses, coated paper and complex protection membranes.
In the forming area, he pointed to fabrics with a plain-weave top surface with support shute binding technology that eliminates interlayer wear Cole said that this design can provide very high fiber support, a wide range of permeabilities, and very thin caliper.
Also, much higher steady state permeabilities were observed than predicted by the Maxwell model.
It is based on correlations between permeabilities and mercury capillary pressure measurements on samples from carbonates and sandstone formations.
Five soft magnet grades have permeabilities from 2.
Higher permeabilities are usually associated with coarser sand.
