I agree. Something wrong in this value. The greater the ratio "mean free path to diameter" is, the closer we get to molecular flow, and the molecules interact with the walls and not with each other. — Preceding unsigned comment added by Navidor (talk • contribs) 15:58, 27 February 2012 (UTC)[reply]

When the mean free path of the molecules in the gas is less than or equal to the diameter of the tube, the molecules will interact more often with the walls of the tube than with each other.

Shouldn't that be, when the mean free path is more than the diameter of the tube they interact more with the walls than with each other? — Preceding unsigned comment added by 109.145.82.127 (talk) 01:08, 19 February 2012 (UTC)[reply]
