3 cards from this section. Quick, good the night before a test.
What is the void ratio if the volume of voids is 0.4 m³ and the volume of solids is 0.6 m³?
Use the formula e = V_v / V_s.
How is porosity calculated?
Remember to multiply by 100 to convert to a percentage.
What is the formula for void ratio?
Think about how voids relate to solids in volume.
True or False: Bulk unit weight is the weight of solids plus water per unit volume.
Recall what elements are included in bulk unit weight.
Calculate the bulk unit weight of a soil sample if its dry weight is 1.6 tons, moisture content is 15%, and volume is 1 m³.
Consider how to convert moisture content into a weight contribution.
Describe the effect of increasing void ratio on the saturated unit weight of soils.
Examine the interplay between voids and saturation in soils.
