Enskog and van der Waals play hockey

摘要: We consider the mean free path of a hockey puck in system other pucks on an air table, and show how simple low‐density kinetic‐theory value for this can be extended to higher densities. This approach is connected both with Enskog theory transport properties dense gases van der Waals equation state gases. derive several approximations high‐density path, compare results each other, accurate computer‐simulation results, experimental obtained freshman physics laboratory University Maryland. present arguments simplified more elaborate forms.
