2. A soil sample has a porosity of 40%. The specific gravity of the solids could be determined by the equation below, Specific gravity, G, = (Student ID)/10° + A If the student number starts with 14, A = 1.25 If the student number starts with 13, A = 1.35 Otherwise, A = 1.9 Take G, till 2 decimal places. Now based on porosity and specific gravity calculate, a. Void ratio b. Dry density c. Unit weight if the soil is 50% saturated d. Unit weight if the soil is completely saturated. (10)
