Mean Free Path Calculator

In Physics, the average travel distance of a moving particle such as atom, molecule, or photon during molecular collision is known as mean free path. During molecular collision, the direction or the energy of the gas molecules changes. This calculator helps in estimating the mean free path of transport properties given the required values.

Formula:

l = 1 / ( √( 2 ) * πd2n ) Where, l=Mean Free Path of Transport Properties d=Molecular Diameter n=Particle Number Density

Mean free path in transport properties is also used to estimate the size of atoms or molecules and the resistivity of material.
