Question

From Geotechnical Engineering class

Soil sample A and sample B each weigh 1 kN. Sample A is 100% saturated and sample B is 50% saturated. Is it possible for sample B to have more water than sample A? Explain. 2. 3. For a given soil, the following parameters are known: void ratio 0.68, specific gravity 2.75, moisture content-15%. Determine dry unit weight moist unit weight (total unit weight) water content at S=100% saturated unit weight (total unit weight when S=100%) 4. A soil that is completely saturated has a unit weight of 20 kN/m2, and a water content of 24%. Assume that G,-2.7, what is the unit weight of the solids? what is the dry unit weight of the soil? Include a phase diagram. Prepare a spreadsheet plot with dry unit weight on the y-axis and water content on the x-axis. Assume that G,-2.7, Plot four curves, with S-40%, S-60%, S-80% and Ss]00%. 5.

Answer 1

2) Yes. There is a possibility. If void ratio of the sample is more than sample A then there is a chance of being more water in B. If void ratio of B is double than A, then water content will be equal in Both A and B.(keeping specific gravity constant). If void ratio of B is more than double of A then water content of B is more than A.
