DIFFUSION OF WATER VAPOR INTO ARTIFICIAL SOILS

In an effort to resolve the problem of whether a certain soil will support a given vehicle under specific weather conditions, preliminary diffusion rate studies in artificial soils were conducted which consisted of tests designed to determine, both analytically and experimantally, the rates at which artificial soils reach an equilibrium point. Consideration was given to such factors such as temperature, vapor pressure, relative humidity, soil composition, experimental conditions, boundary and surface conditions of soil etc. Some of the factors are considered constant to allow analytic correlation between idealized and experimental data. The data obtained are tabulated or plotted in graphs. A comparison of the experimental and calculated diagrams shows the analogy between heat transfer and diffusion to the quite close.
