3.10 Refer to Problem 3.9. Determine the weight of water, in kN, to be added per cubic meter (m³) of soil for a. 90% degree of saturation b. 100% degree of saturation 3.11 The moist density of a soil is 1750 kg/m³. Given w = 23% and G, = 2.73, determine: a. Dry density b. Porosity c. Degree of saturation d. Mass of water, in kg/m³, to be added to reach full saturation. 3.9 For a given soil, the following are known: G, = 2.74, moist unit weight, y = 20.6 kN/m³, and moisture content, w = 16.6%. Determine:
