Derivation of mean free path
WebMar 26, 2024 · Taking into account the Maxwell-Boltzmann speed distribution, the mean free path is then shortened by the factor 1/√2 (the derivation of this factor is shown in the last section): λ = 1 √2nπd2 n = N … WebJan 26, 2012 · mean free path. Average distance a molecule travels in a gas between collisions. This concept has a meaning only to the extent that the paths of molecules are mostly straight lines interrupted by changes in direction (collisions) over comparatively shorter distances of order the molecular size. Molecules in a liquid are never free in this …
