1.1. Constant Head Flow

Try these first

1. 1.

   What is the main purpose of a constant head permeameter?

   Hint

   Think about soil types in relation to water flow.

2. 2.

   What does Darcy's Law relate to?

   Hint

   Consider fluid dynamics.

3. 3.

   What type of soil is most appropriately tested using a constant head permeameter?

   • Fine-grained
   • Coarse-grained
   • Clay

   Hint

   Think about the characteristics of the soil.

4. 4.

   True or False: The falling head permeameter can be used for coarse-grained soils.

   • True
   • False

   Hint

   Consider the nature of the soils.

5. 5.

   How would the permeability of a sample change if additional fine particles were mixed into a coarse soil?

   Hint

   Consider the impact of mixed soil textures on water movement.

6. 6.

   Given a fine-grained soil with a known dropping head over time, derive how you would measure the final permeability.

   Hint

   Use the falling head equation to assist your calculations.
