2 cards from this section. Quick, good the night before a test.
Define dry unit weight.
Think of it as weight without any liquid.
What does moisture content represent?
It's a percentage!
What is the formula to calculate dry unit weight?
Recall how moisture content affects the weight.
True or False: Specific gravity is the weight of soil solids in comparison to water.
Think of it as a comparative measure.
Given a soil sample with a specific gravity of 2.68 and a void ratio of 0.65. Calculate the dry unit weight when the bulk density is known to be 18 kN/m³.
Make sure to use the relationship of specific gravity and void ratio properly.
A soil sample has a moisture content of 15%. If the moist unit weight is found to be 21 kN/m³, what is its dry unit weight?
Convert the percentage to decimal before applying.
