Abstract
The flow and electrical properties of water of conductivity ranging from 0.1 Ohm-1-meter-1 to about 10-4 ohm-1-meter-1 were studied in synthetic porcelain porous samples of average pore radius 0.42 Microns. Streaming potential and surface conductance were measured by standard techniques. The electroviscous effect was measured by shorting out the streaming potential electrodes and observing the resultant change in flow rate. The experimental results are compared with curves calculated from theoretical expression by two different authors. The results indicate that neither theory completely explains the processes which occur. Several hypotheses are advanced to account for the discrepancies.
