## Volume of water formula

$$\large{ V_w = k \; i \; A_c \; t }$$
Symbol English Metric
$$\large{ V_w }$$ = volume of water $$\large{ft^3}$$ $$\large{m^3}$$
$$\large{ A_c }$$ = area cross-section $$\large{ft^2}$$ $$\large{m^2}$$
$$\large{ t }$$ = duration of time for collection of water $$\large{sec}$$ $$\large{s}$$
$$\large{ i }$$ = hydraulic gradient $$\large{dimensionless}$$
$$\large{ k }$$ = permeability coefficient $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
