Relation between void ratio and porosity

The relation between porosity and void ratio, if void ratio is unknown

\[e = \frac{n}{{1 - n}}\]

The relation between porosity and void ratio, if porosity is unknown

\[n = \frac{e}{{1 + e}}\]

The void ratio (e) a mixture is the ratio of the volume of voids to volume of solids.

\[e = \frac{{{V_V}}}{{{V_S}}}\]

The porosity (n) a mixture is the ratio of the volume of voids to total volume.The value is expressed in percentage ranges between 0 to 100% or ( 0 to 1)

\[n = \frac{{{V_V}}}{{{V_T}}}\]
