A small amount of solvent is added to the ground water to change its electrolytic content. As a result, the contacting angle, 0, representing the adhesion between water and soil material, is increased from 30° to 42° while the surface tension decreases by 10 percent (Figure P 1.5.5). The soil has a uniform pore size of 0.7 mm. Determine the change of capillary rise in the soil.
