Witryna15 paź 2024 · VELOCITY/AREA METHOD. This depends on measuring the average velocity of flow and the cross-sectional area of the channel and calculating the flow from: Q (m 3 /s) = A (m 2) x V (m/s) The metric unit m 3 /s is referred to as the cumec. Because m 3 /s is a large unit, smaller flows are measured in litres per second (l/s).
