flow volumetricVolumetric flow rate, abbreviated as Q, also called volume flow rate, is the amount of fluid that flows in a given time past a specific point.

 

Volumetric flow rate formula

\(\large{ Q = \frac{ V }{ t } }\)
Symbol English Metric
\(\large{ Q }\) = volumetric flow rate \(\large{\frac{ft^3}{sec}}\) \(\large{\frac{m^3}{s}}\)
\(\large{ t }\) = time \(\large{sec}\) \(\large{s}\)
\(\large{ V }\) = volume \(\large{ in^3}\) \(\large{ mm^3}\)

 

Volumetric flow rate formula

\(\large{ Q = \frac{ A_c \; l }{ t } }\)
Symbol English Metric
\(\large{ Q }\) = volumetric flow rate \(\large{\frac{ft^3}{sec}}\) \(\large{\frac{m^3}{s}}\)
\(\large{ A_c }\) = area cross-section \(\large{ in^2}\) \(\large{ mm^2}\)
\(\large{ l }\) = length of volume \(\large{ ft }\) \(\large{ m }\)
\(\large{ t }\) = time \(\large{sec}\) \(\large{s}\)
