The flow of a gas through a small aperture. The relative rates at which gases effuse, under the same conditions, is approximately inversely proportional to the square roots of their densities.

Chemical Engineering
The flow of gases under pressure through small holes such as a gas escaping from a cracked weld on a process vessel. The rate of flow is inversely proportional to the density. Comparediffusion.
