Hello all! Can you please provide some guidance with this problem? 1. The problem statement, all variables and given/known data Calculate the air pressure at 3000m above sea level assuming that the molecular weight of air is 29 and the ambient temperature is constant against height. 2. Relevant equations Stokes-Einstein equation. In fact, brownian motion was the focus of the class but I fail to understand how it can be applied to the problem above. Thank you! Any help is much appreciated!
