DEPARTMENT OF CHEMICAL ENGINEERING PROGRESS REPORT NO. 6, FEBRUARY 1, 1960- SEPTEMBER 1, 1960. PART II. SOIL PERCOLATION STUDIES
The seepage of liquids through soils is studied by correlating the effects of particle diameter of the soils on flow. Particle diameters are calculated to make the data fit the Carman and Kozeny equations as modified by Ergun for flow through porous media. If the effective diameters of the particles are known for the narrow ranges of sieve sizes, then it may be possible to predict the flow through soil mixtures of all particle sizes provided the effective diameters of all ranges of sieve sizes in the soil are known. The results of the work thus far indicate that this method of approach to the problem of predicting flow rates of liquids through soils looks very promising. It was found in the tests on the individual range of sieve sizes that there was little difference between the flow rates of neutral water and water with pH 3. This was also true of water of pH 10 through the range 40 --45. With particles smaller than 40 --45 mesh, flow of water at pH 10 continued to decrease indicating that complete plugging of the samples would eventually occur. (N.W.R.)
