WebFlow rate Q is defined to be the volume of fluid passing by some location through an area during a period of time, as seen in Figure 12.2. In symbols, this can be written as. 12.1 Q = V t, where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. WebThe volumetric flow rate (Q) can be computed as the product of the cross-sectional area (A) for flow and the average flow velocity (v) as follows: Q = A * v. Example: Let's say we have a circular channel that has an inner diameter of 8 inches. Water is flowing through the channel at an average velocity of 16 feet per second.
