partially saturated soil 1Porosity, abbreviated as n, a dimensionless number, is the ratio between the pore volume of a substance and its total volume.  Porosity of a measure of a rocks capacity to store fluids.


Porosity formula

\(\large{ n = \frac {V_v} {V_t } }\)
Symbol English Metric
\(\large{ n }\) = porosity \(\large{dimensionless}\)
\(\large{ V_t } \) = total volume of soil \(\large{ft^3}\) \(\large{m^3}\)
\(\large{ V_v }\) = volume of voids (air and water) \(\large{ft^3}\) \(\large{m^3}\)
