WebThe following is the mean free path of particles in a gas equation λ = k * T / (√2 * π * d² * p) Where, λ = mean free path. k = Boltzmann constant (k = 1.380649 x 10-23 J/K) T = temperature of the gas. d = diameter of the particle. p = pressure of the gas. To do appropriate computations, the mean free path formula requires atomic diameter. Webmean free path, average distance an object will move between collisions. The actual distance a particle, such as a molecule in a gas, will move before a collision, called free path, cannot generally be given because its calculation would require knowledge of the path of every particle in the region.
