Abstract
AbstractRate of flow of moisture in unsaturated porous materials at constant temperature depends upon the gradient of the moisture potential, the size of the flow channel, and other factors relating to the fluid and porous medium but which may be held constant. Size of the flow channel likewise is continually changing. An experimental technique has been devised for direct measurement of the velocity of water movement in materials simulating soils. From these data, with the aid of moisture density measurements, rate of flow can be obtained. Velocity data obtained by this technique are being used to study the mechanics of flow under unsaturated conditions. Further information has been obtained on the nature of the f‐function in the equation, v = k f grad Φ, where v is velocity of flow, k is saturated permeability, and Φ is moisture potential.
