We use the Falling Head Permeability Test to evaluate the permeability of fine-grained soils with low permeability, such as silts and clays, by measuring the rate of water flow as the water head decreases over time. To measure hydraulic conductivity in this test, saturate the soil sample until it produces a constant flow (Q) from the bottom of .
In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (), is a measure of the electric polarizability of a dielectric material. A material with high permittivity polarizes more in response to an applied electric field than a material with low permittivity, thereby storing more energy in the material. Therefore, based on the technical advantages of HVEP fracturing technology for coal–rock permeability enhancement, in this study, a multi-field coupling (of various parameters such as in-situ stress field, gas seepage field, and electric field) HVEP fracturing coal–rock permeability enhancement physical simulation test device and test .

Two general types of permeability test methods are routinely performed in the laboratory: (1) the constant head test method, and (2) the falling head test method. The constant head test method is used for cohesionless and more permeable soils (k>10-4 cm/s) and the falling head test is mainly used for cohesive or less permeable soils (k<10-4 cm . differential permeability µ = Δ B /Δ H, rather than the permeability µ = B/H, which is commonly used with soft-magnetic materials.
