Knudsen Number Calculator

The Knudsen number (K_n) is a dimensionless quantity used to determine the relative importance of molecular effects in a gas or fluid flow. It is stated as the ratio of the molecule’s mean free path and the system’s characteristic length scale. The mean free path is the average distance a molecule travels between collisions while the characteristic length scale represents the relevant dimensions of the system.
Knudsen Number Calculator is a tool that is used to find the molecular effect of the fluid or gases by the ratio of the mean free path and physical length scale.
