Mean path formula
WebIn reality, the mean free path cannot be calculated by taking the average of all the paths because it is impossible to know the distance of each path traveled by a molecule. However, we can calculate it from the average speed ( c ) of the molecule divided by the collision frequency ( Z ). The formula for this is: λ = c Z. WebDec 26, 2024 · Figure 2.

In the kinetic theory of gases, the mean free path of a particle, such as a molecule, is the average distance the particle travels between collisions with other moving particles. The derivation above assumed the target particles to be at rest; therefore, in reality, the formula holds for a beam particle with a high speed relative to the velocities of an ensemble of identical particles with random locations. In that case, the motions of target particles are comparatively negligible, henc… WebOct 10, 2024 · In fact, the ratio of the mean-free-path over the Debye length has the same formula as in the classical case. Namely, the functional dependence on the polytropic index is identical for the ratio of the mean-free-path over the Debye length λ mfp /λ D and the Debye number N D , e.g., γ 3/2 ; hence, the ratio λ mfp /λ D can be expressed as a ...
