Flow proportional weir
WebDischarge through the aforementioned weir is proportional to the depths of flow measured above the crest of the weir for all heads in the range of 0.5R -< h ~< 7.9R, within a maximum deviation of -+ 1% from the theoretical discharge. ... Linear-proportional weirs that give a linear head-discharge relationship have been extensively studied ... WebOnce the upstream water level exceeds the crest height of the weir, the water will start flow over the weir. As the depth of water above the weir, h 1 increases, the discharge over the weir, Q will also increases correspondingly. The ideal relationship between h 1 and Q may readily derive for each weir shape based on the basis of the
