Question

The value of porosity of a soil sample in which the total volume of soil grains is equal to twice the total volume of voids would be

• A. 75%
• B. 66.66%
• C. 50%
• D. 33.33%

Answer 1

The correct option is D 33.33%

(d)

$Given,V_s=2V_V$

$Voidratio,e=\frac{V_V}{V_s}=0.5$

$Porosity,n=\frac{e}{1+e}=\frac{05}{1.5}=\frac{1}{3}$

or 33.33%
