A soil has a void ratio of 0.5. The total porosity of the soil is____. (Round off to two decimal places)
Correct Answer: 0.33
Solution and Explanation
To find the total porosity of soil with a given void ratio, we can use the relationship between void ratio (e) and porosity (n), expressed by the formula:
n = e / (1 + e)
Given the void ratio e is 0.5, substitute this value into the formula:
n = 0.5 / (1 + 0.5) = 0.5 / 1.5
Perform the division to find the total porosity:
n = 0.3333...
Rounding to two decimal places, the porosity is:
n = 0.33
