Void ratio (e):
Void ratio is usually defined as the ratio of the volume of voids to the total volume of soil solid.
Porosity (n):
Porosity is defined as the ratio of the volume of voids to the total volume of the soil.
The relationship between void ratio and porosity are as follows:
\(\rm{e=\frac{n}{1-n}\; and\; n=\frac{e}{1+e}}\)
Calculation:
Given, V = 50 ml
Volume of water displaced = volume of solids
VS = 30 ml
Volume of voids, VV = V – VS = 50 – 30 = 20 ml
\(\therefore {\rm{e}} = {\rm{\;}}\frac{{{{\rm{v}}_{\rm{v}}}}}{{{{\rm{V}}_{\rm{s}}}}} = {\rm{\;\;}}\frac{{20}}{{30}} = 0.667\) = 66.67 %
