Flow rate equations
WebJan 24, 2024 · The SI unit of flow rate is m 3 /s, but other rates can be used, such as L/min. Flow rate and velocity are related by Q = Av where A is the cross-sectional area of the … WebThe volume of fluid passing by a given location through an area during a period of time is called flow rate Q, or more precisely, volume flow rate. In symbols, this is written as. Q = d V d t. 14.13. where V is the volume and t is the elapsed time. In Figure 14.26, the volume of the cylinder is Ax, so the flow rate is.
