Darcy Velocity or Flux formula

\(\large{ v =  k \; i   }\)

Where:

Units	English	Metric
\(\large{ v }\) = Darcy velocity or flux	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
\(\large{ k }\) = hydraulic conductivity	\(\large{\frac{ft}{day}}\)	\(\large{\frac{m}{day}}\)
\(\large{ i }\) = hydraulic gradient	\(\large{dimensionless}\)

Solve For:

\(\large{ k = \frac{ v }{ i }   }\)
\(\large{ i = \frac{ v }{ k }   }\)
