Is the 'Mean Free Path' defined only for the gas phase? Is there any approximation for the mean free path of a liquid such as water?

In physics, the mean free path is the average distance traveled by a moving particle (such as an atom, a molecule, a photon) between successive impacts (collisions),[1] which modify its direction...
