Penetration of a liquid, gas, or vapor through a solid
In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity.[1] Permeation is modeled by equations such as Fick's laws of diffusion, and can be measured using tools such as a minipermeameter.
