Calculate the dry unit weight if the moist unit weight is 18 kN/m³ and moisture content is 0.15.
Use the formula γ_d = γ / (1 + w)
Define the term 'unit weight' as it pertains to soil.
Think about how we measure weight in soil conditions.
What is the formula for dry unit weight?
Remember the relationship taught in class.
True or False: Saturation occurs when air fills the voids in soil.
Think about how water affects the voids.
Given a moist unit weight of 22 kN/m³ and moisture content of 20%, calculate the dry unit weight and the amount of water needed to saturate it assuming the saturated unit weight is 25 kN/m³.
Start by calculating dry unit weight and then the water required.
A soil's void ratio is 0.5, and specific gravity is 2.7. Calculate the dry unit weight and then the moist unit weight given a moisture content of 15%.
Remember the formulas and plug in values step-by-step.
