Abstract
A theory for thermal transpiration based on the dusty‐gas model has been proposed by Mason, Evans, and Watson. For verification the theory ideally requires both nonisothermal and isothermal measurements on a sample of porous material. Such measurements are reported and it is found that the dusty‐gas theory satisfactorily reproduces the experimental results except when the gas adsorbed appreciably on the sample.Keywords
