The value ofG, is 2.70. Calculate the void ratio and degree of saturation of the soil. What wouldbe the values of density and water content if the soil were fully saturated at thesame void ratio?3.3 Calculate the dry unit weight, the saturated unit weight and the buoyant unit weightof a soil having a void ratio of 0.70 and a value of G, of 2.72. Calculate also theunit weight and water content at a degree of saturation of 75%.3.4 A soil specimen is 38mm in diameter and 76mm long and in its natural conditionweighs 168.0g. When dried completely in an oven the specimen weighs 130.5g.The value of G, is 2.73. What is the degree of saturation of the specimen?3.5 The in-situ dry density of a sand is 1.72Mg/m. The maximum and minimum drydensities, detemmined by standard laboratory tests, are 1.81 and 1.54Mg/m',respoctively. Determine the density index of the sand.
