1.1. Void Ratio (e)

Try these first

1. 1.

   What is the void ratio if the volume of voids is 20 m³ and volume of solids is 80 m³?

   Hint

   Use the formula e = V_v / V_s.

2. 2.

   Define porosity in your own words.

   Hint

   Think about how voids relate to total volume.

3. 3.

   What is the void ratio if the volume of voids is 30 m³ and the volume of solids is 60 m³?

   • 0.5
   • 1.5
   • 2.0

   Hint

   Think about how to set up the fraction.

4. 4.

   True or False: The degree of saturation can exceed 100%.

   • True
   • False

   Hint

   Consider what it means to be saturated.

5. 5.

   A soil sample's void ratio is identified as 0.8. Calculate the porosity and degree of saturation if the total volume is 100 m³ and water occupies 40 m³.

   Hint

   Start by finding solids from void ratio and total volume relationship.

6. 6.

   If a soil has a void ratio of 1.2, and its bulk density is known to be 18 kN/m³, what can be said about the specific gravity of the solids?

   Hint

   Rearranging relationships helps explore soil physical characteristics.
