In falling head permeability test the initial head was 350 mm and the final head was 60 mm. The cross-sectional area of the burette was 200 mm2. The sample was 50 mm in diameter and 105 mm long. If the test took 8 hours and 30 minutes, what was the coefficient of permeability of the soil in m/s?
Determine the degree of saturation in percentage in a bulk density determination procedure on a sample of clay with a mass of 683 gm which was coated with paraffin wax. The combined mass of clay and wax was 690.3g. The volume of clay and paraffin wax was found out to be 340 ml. The sample moisture content and specific gravity of soil solids are 16% and 2.73 respectively. Assume specific gravity of the wax as 0.89.
An undisturbed soil sample was prepared for a triaxial testing. The cylindrical soil sample is 50 mm in diameter and 100 mm long. It has a mass of 360 g. After finding the mass of the entire sample, a small portion was removed and a moisture content test was performed on it. The result of the moisture content test is shown in Table 3(a). Given the specific gravity, G, is 2.70. (i) Compute the moisture content (%) of the soil sample. (ii) By using the soil phase diagram, determine the bulk density (kg/m³), dry density (kg/m³), void ratio, porosity (%) and degree of saturation (%) of the soil sample.
