Volumetric Flow Rate

flow volumetricVolumetric 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  \(\large{in^3}\) \(\large{mm^3}\)
