Volume of water formulas

\(\large{ V_w =  k \; i \; A_c \; t   }\)   
\(\large{ V_w =  k \; A_c \; t \; \frac{ h_l }{ L }    }\)  
\(\large{ V_w =  \frac{ S \; e \; V_t }{ 1 \;+\; e }   }\)   

Where:

 Units English Metric
\(\large{ V_w }\) = volume of water \(\large{ft^3}\) \(\large{m^3}\)
\(\large{ A_c }\) = area cross-section \(\large{ft^2}\) \(\large{m^2}\)
\(\large{ S }\) = degree of saturation \(\large{dimensionless}\)
\(\large{ t } \) = duration of time for collection of water \(\large{sec}\) \(\large{s}\)
\(\large{ h_l }\) = head loss \(\large{ft}\) \(\large{m}\)
\(\large{ i } \) = hydraulic gradient \(\large{dimensionless}\)
\(\large{ L } \) = length of the sample \(\large{ft}\) \(\large{m}\)
\(\large{ k } \) = permeability coefficient \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ V_t } \) = total volume of soil \(\large{ft^3}\) \(\large{m^3}\)
\(\large{ e }\) = void ratio  \(\large{dimensionless}\)
