The mean free path of a gas molecule formula

Splet3.8 Mean Free Path and Diffusion In a gas, the molecules collide with one another. Momentum and energy are conserved in these collisions, so the ideal gas law remains valid. The mean free path λ is the average distance a particle travels between collisions.

The mean free path of a gas molecule formula

Did you know?

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… Splet09. apr. 2024 · Abstract A method for solving the Boltzmann equation is presented that makes it possible to calculate gas flows in the continuum flow regime described by the Navier–Stokes equations. Progress into the region of continuum flows was achieved by applying the conservative projection method for calculating the Boltzmann collision …
