In electromagnetism, permeability is the measure of magnetization produced in a material in response to an applied magnetic field.Permeability is typically represented by the (italicized) Greek letter μ.It is the ratio of the magnetic induction to the magnetizing field as a function of the field in a material. The term was coined by William Thomson, 1st Baron Kelvin in 1872, [1] and .Gas Permeability tester involves measurement of flow rate of a fluid across a sample and the pressure drop across it in order to compute permeability using Darcy’s law. Gas flow rates and pressure drops are also used to compute many other useful characteristics of porous media. Measurement of flow rates of different gases can also permit pore .Constant Head Permeability Test The constant head permeability test is a laboratory experiment conducted to determine the permeability of soil. The soils that are suitable for this tests are sand and gravels. Soils with silt content cannot be tested with this method.The test can be employed to test granular soils either reconstituted or disturbed.
Air permeability is a widely used test which measures how easily air is passed through fabric and helps to indicate the fabric’s breathability, particularly for wind-resistant, weather-resistant and waterproof fabrics.
Trenchlesspedia Explains Permeability Test. There are two methods to perform the soil permeability test – the constant head method and the falling head method. In the constant head test, the same relative elevation of the top of the water column remains over the sample for the entire duration of the test.
