Gas permeability units conversion

The permeation of a material can be measured through numerous methods that quantify the permeability of a substance through a specific material. Permeability due to diffusion is measured in SI units of mol/ (m･s･Pa) although Barrers are also commonly used. See more 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 See more Abbé Jean-Antoine Nollet (physicist, 1700–1770) Nollet tried to seal wine containers with a pig's bladder and stored them under water.
