Volumetric Flow Rate

Volumetric flow rate, abbreviated as Q, also called flow rate, is the amount of fluid that flows in a given time past a specific point or you could say the actual volume flow.

 

Volumetric flow rate formulas

\(\large{ Q = A_c \; v }\)

\(\large{ Q = A_c \; v \; cos \; \theta }\)

\(\large{ Q = \frac {V} {t} }\)

\(\large{ Q = k \; i \; A_c }\)

Where:

Units	English	SI
\(\large{ Q }\) = volumetric flow rate	\(\large{\frac{ft^3}{sec}}\)	\(\large{\frac{m^3}{s}}\)
\(\large{ A_c }\) = area cross-section	\(\large{ft^2}\)	\(\large{m^2}\)
\(\large{ k }\) = hydraulic conductivity	\(\large{\frac{ft}{day}}\)	\(\large{\frac{m}{day}}\)
\(\large{ i }\) = hydraulic gradient	\(\large{dimensionless}\)
\(\large{ t }\) = time	\(\large{sec}\)	\(\large{s}\)
\(\large{ v }\) = velocity	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
\(\large{ V }\) = volume	\(\large{in^3}\)	\(\large{mm^3}\)
