The mean free path of the FHP hydrodynamical models is calculated. The calculations show that the mean free path is approximate to a constant after more than 60 collisions and is a minimum, which is corresponding to the maximum of Reynolds' number, when particle density is 0.25. In addition, the difference between the FHP models and the molecular dynamic models is showed clearly.
