Flow Rate
Flow rate, abbreviated as Q, measure the amount of fluid that flows in a given time past a specific point.
Flow Rate formulas
| \(\large{ Q = A \; v }\) | |
| \(\large{ Q = C_v \; \sqrt {\frac{SG} {\Delta p} } }\) | (flow coefficient) |
| \(\large{ Q = k \; i \; A_c }\) | (hydraulic gradient) |
| \(\large{ Q = \frac{ 3960 \; WHP }{ h_t } }\) | (water horsepower) |
Where:
\(\large{ Q }\) = flow rate
\(\large{ A }\) = area
\(\large{ A_c }\) = area cross-section of flow
\(\large{ C_v }\) = flow coefficient
\(\large{ k }\) = hydraulic conductivity
\(\large{ i }\) = hydraulic gradient
\(\large{ \Delta p }\) = pressure differential
\(\large{ SG }\) = specific gravity of fluid (water at 60°F = 1.0000)
\(\large{ h_t }\) = total head or height
\(\large{ v }\) = velocity
\(\large{ WHP }\) = water horsepower
