Volume of Void
Volume of void, abbreviated as V_v, is the ratio of total volume of soil minus volume of solid soil.
Volume of Void formulas
| \(\large{ V_v = V_t - V_s }\) | |
| \(\large{ V_v = V_w + V_a }\) | |
| \(\large{ V_v = n \; V_t }\) | (porosity) |
| \(\large{ V_v = e \; V_s }\) | (void ratio) |
| \(\large{ V_v = \frac{ e \; V_t }{ 1 \;+\; e } }\) |
Where:
\(\large{ V_v }\) = volume of void
\(\large{ n }\) = porosity
\(\large{ V_t } \) = total volume of soil
\(\large{ e }\) = void ratio
\(\large{ V_a } \) = volume of air
\(\large{ V_s } \) = volume of solid soil
\(\large{ V_w } \) = volume of water
\(\large{ w } \) = water content
