1. Of a magnetic material, the ratio of the magnetic induction to the magnetic field intensity in the same region. 2. The ability to permit penetration or passage. In this sense the term is applied particularly to substances which permit penetration or passage of fluids.3. = permeability coefficient. (references)

The percentage volume of a space that can be flooded. When a compartment contains cargo, fuel, etc. the amount of water which can enter on damage is less than the volume of the empty compartment. Source: European Union. (references)

Geography

Ability of water to penetrate soil measured as quantity per area, time and pressure gradient and usually indicated in m/s. Source: European Union. (references)

Geological

The ability of a rock or other material to allow water to flow through its interconnected spaces. Permeable bedrock makes a good aquifer, a rock layer that yields water to wells. See porosity. (3 MB porosity animation available). (references)

Hydrologic

The ability of a material to allow the passage of a liquid, such as water through rocks. Permeable materials, such as gravel and sand, allow water to move quickly through them, whereas unpermeable material, such as clay, don't allow water to flow freely. (references)

Mining

A. The permeability (or perviousness) of rock is its capacity for transmitting a fluid. Degree of permeability depends upon the size and shape of the pores, the size and shape of their interconnections, and the extent of the latter. It is measured by the rate at which a fluid of standard viscosity can move a given distance through a given interval of time. The unit of permeability is the darcy. See also:millidarcy; coefficient of permeability b. In geophysics, the ratio of the magnetic induction to the magnetic intensity in the same region. In paramagnetic matter, the permeability is nearly independent of the magnetic intensity; in a vacuum, it is strictly so. But in ferromagnetic matter, the relationship is definite only under fully specified conditions c. See:coefficient of permeability d. In magnetism, a general term used to express various relationships between magnetic induction and magnetizing forces. These relationships are either absolute permeability, which is the quotient of a change in magnetic induction divided by the corresponding change in magnetizing force, or specific (relative) permeability, the ratio of the absolute permeability to the permeability of free space e. In founding, the characteristics of molding materials which permit gases to pass through them. Permeability number is deteremined by a standard test f. In powder metallurgy, a property measured as the rate of passage underspecified conditions of a liquid or gas through a compact. (references)

Specialty Definition: Permeability

(From Wikipedia, the free Encyclopedia)

In physics and electrical engineering, permeability is the degree of magnetisation of a material in response to a magnetic field. Absolute permeability is represented by the symbol μ.

where B is the magnetic flux density (also called the magnetic induction) in the material and H is the magnetic field strength.

In SI units, magnetic flux density is measured in tesla, magnetic field strength in ampere per metre and permeability in henryss per metre.

Relative permeability, sometimes denoted by the symbol μr and often simply by μ, is the ratio of the absolute permeability to the permeability of free space μ0.

μ0 = 4π × 10-7 N·A-2 (exactly)

In geology, permeability is a measure of the ability of a material (typically, a rock) to transmit fluids. It is of great importance in determining the flow characteristics of hydrocarbons in oil and gas reservoirs and of water in aquifers. The usual unit for permeability is the darcy, or more commonly the milli-darcy or md (1 darcy = 1 x 10-12.m2). Permeability is used to calculate flow-rates using Darcy's law.

For a rock to be considered as an exploitable hydrocarbon reservoir, its permeability must be greater than approximately 100 md (depending on the nature of the hydrocarbon - gas reservoirs with lower permeabilities are still exploitable because of the lower viscosity of gas with respect to oil). Rocks with permeabilities significantly lower than 100 md can form efficient seals (see petroleum geology). Unconsolidated sands may have permeabilities of 5000+ md.
