curprev 00:3200:32, 22 April 2022‎ 96.245.118.124 talk‎ 17,302 bytes +154‎ →‎Kinetic theory of gases: Updated the value of mean free path to be from 64 to 68 nm based on the values in Table 5 of the cited reference (https://doi.org/10.1016/0021-8502(88)90219-4). Also added extra reasons why these values can vary. undo

curprev 00:3500:35, 21 April 2022‎ 96.245.118.124 talk‎ 17,148 bytes +100‎ →‎Kinetic theory of gases: Corrected the formula once more by checking the cited reference "Introduction to physical gas dynamics". The formula in the book uses density rather than pressure in the denominator. The density can derived from pressure using ideal gas law, resulting in the formula that predicts reasonable mean free path (66 nm) at atmospheric pressure and room temperature, consistent with the value in the table below. undo
