Question 1.
What is hydrometer analysis used for?
Show hintHide hint
Think about what types of soil particles are considered fine.
Question 2.
What principle does hydrometer analysis rely on?
Show hintHide hint
What law relates to particles settling in fluids?
3Question 3.
Hydrometer analysis is particularly useful for particles smaller than which size?
- 25 µm
- 75 µm
- 100 µm
Show hintHide hint
Remember the classification of fine-grained soils.
4Question 4.
Stokes' Law indicates that larger particles settle faster than smaller particles.
- True
- False
Show hintHide hint
Think about how size impacts time.
Question 5.
A soil sample contains silt and clay particles suspended in a fluid. If the hydrometer shows a higher density reading at 2 minutes compared to 5 minutes, what does that indicate about the sedimentation process?
Show hintHide hint
Think about what settling indicates about particle size over time.
Question 6.
If you were to apply a different fluid in hydrometer analysis that is denser than water, how would the hydrometer readings change, and why?
Show hintHide hint
Consider the effect of medium density on particle movement.
