How to determine water flow
WebFind the surface water velocity (in m/s) by dividing the distance from AA to BB (in this example, 10 m) by the average time (in seconds) and multiply this result by 0.85 (a correction factor) to estimate the average water velocity of the stream. Average water velocity = 0.5 m/s x 0.85 = 0.425 m/s. Webwater use: 1. Flow meters with a totalizer. 2. Flow rate meters used with timing devices.† ‡ 3. Timing devices (hour meters and electric meters). † ‡ 4. Vehicle gallon capacities (i.e. water trucks).† † Daily records of water use and time pumped must be kept for these methods. ‡ Methods 2 and 3 are require d to have a constant ...
