What is the porosity percentage if the particle density of soil is 2.6 and bulk density is 1.3
Answer & Solution
Correct Answer:
Option
C
If the particle density of soil is 2.6 and bulk density is 1.3 then the porosity percentage will be:
$$\eqalign{ & {\text{Soil porosity}} = \left( {1 - \frac{{{\text{Bulk Density}}}}{{{\text{Particle Density}}}}} \right) \times 100 \cr & = \left( {1 - \frac{{2.6}}{{1.3}}} \right) \times 100 \cr & = 0.5 \times 100 \cr & = 50\% \cr} $$
$$\eqalign{ & {\text{Soil porosity}} = \left( {1 - \frac{{{\text{Bulk Density}}}}{{{\text{Particle Density}}}}} \right) \times 100 \cr & = \left( {1 - \frac{{2.6}}{{1.3}}} \right) \times 100 \cr & = 0.5 \times 100 \cr & = 50\% \cr} $$
