Question

A soil has a void ratio of 0.50. Then its porosity is:

• A. 3
• B. \( \frac{1}{3} \)
• C. 2
• D. \( \frac{1}{2} \)

Hint:

Use the formula: \( n = \frac{e}{1 + e} \) where \( e \) is the void ratio.

Answer 1

The Correct Option is B

Porosity \( n \) is related to void ratio \( e \) by: \[ n = \frac{e}{1 + e} = \frac{0.50}{1 + 0.50} = \frac{0.50}{1.50} = \frac{1}{3} \]
