Permeability is a property that describes the ease with which a substance can pass through a material or medium. In science and engineering, permeability is contextualized for different transport processes and typically depends on the medium, the transported species, and environmental conditions.
Magnetic permeability (mu) measures how a material responds to a magnetic field. It is often expressed as
Hydraulic permeability characterizes fluid flow through porous media and is described by Darcy’s law. The intrinsic
Gas and vapor permeability concerns the transmission of gases through solids, particularly polymers and films. The
Biological membranes exhibit permeability to water and solutes, governed by concentration gradients, osmotic pressure, and the
Overall, permeability bridges material structure and transport behavior, informing applications across soils, energy, materials science, and
