A small amount of solvent is added to the ground water to change its electrolytic content. Asa result, the contacting angle, ?, representing the adhesion between water and soil material, isincreased from 30° to 42° while the surface tension decreases by 10 percent. The soil has auniform pore size of 0.7 mm. Determine the change of capillary rise in the soil.

A stratum of sand and a stratum of clay have the same thickness of 3 m. The coefficient of compressibility of sand is one fifth of coefficient of compressibility of clay and the permeability of sand is 10,000 times that of the clay. Assuming the same initial void ratio the ratio of the consolidation time for the clay to that of the sand for same degree of consolidation is
