Example Problems

Problem 1: A soil sample has a moist unit weight of $19.2 \, kN/m^3$ and a water content of $12\\%$. The specific gravity of solids is 2.68. Find the dry unit weight, void ratio, and degree of saturation.

Problem 2: A saturated clay sample has a water content of $40\\%$ and a specific gravity of $2.70$. Determine the void ratio and porosity.

Problem 3: A partially saturated soil sample has a total volume of $0.05 \, m^3$ and weighs $800 \, N$. After drying in an oven, it weighs $700 \, N$. The specific gravity of the soil solids is $2.65$. Determine the water content, bulk unit weight, dry unit weight, void ratio, and degree of saturation. Assume $\gamma_w = 9.81 \, kN/m^3$.
