Problem 1 A 0.35-m3 moist soil sample has the following: Moist mass of 711.2 kg, Dry mass of 623.9 kg, and Specific gravity of soil solids of 2.68. Calculate: a) Moisture content, b) Moist density, c) Dry density; d) Void ratio; e) Porosity. Problem 2 The moist weight of 0.25 ft of a soil is 23 lb. The moisture content and the specific gravity of the soil solids are determined in the laboratory to be 11% and 2.7, respectively. Calculate: a) Moist unit weight (lb/ft"), b) Dry unit weight (lb/ft"), c). Void ratio, d). Porosity, e). Degree of saturation (%), f). Volume occupied by water (ft")? Problem 3 The saturated unit weight of a soil is 19.8 kN/my. The moisture content of the soil is 16.1%. Determine the following: a). Dry unit weight, b). Specific gravity of soil solids; c) Void ratio Problem 4 For a given soil, the following are given: Gs = 2.67; moist unit weight = 113 lb/ft"; and moisture content, w = 10.3%. Determine: a). Dry unit weight, b). Void ratio, c). Porosity, d). Degree of saturation. Problem 5 For Problem 4 soil, Determine the weight of water, in pounds, to be added per cubic foot of soil for: a) 80% degree of saturation, b) 100% degree of saturation. Problem 6 The moist unit weight of a soil is 114 lb/ft at a moisture content of 10%. Given G = 2.68, determine: a) void ratio, b) Saturated unit weight.
