SHARP CRESTED RECTANGULAR WEIR Sharp crested rectangular weir is a thin vertical plate provided in an open channel to estimate the discharge. The edge of the sharp crested weir is bevelled on the downstream side to …
WebbSharp-crested weirs, commonly referred to as notches, are manufactured from sharp-edged thin plates. The relationship between the flow rate and water depth above the weir can be derived by applying the Bernoulli’s … Webb23 jan. 2024 · Bin Shaharin (2013) showed in a numerical study that the important variable governing discharge over sharp-crested weir was the water head over weir per weir divided by weir height, h/P. He also highlighted the advantages of an ANSYS CFX-14 as a tool for examining velocity vectors and pressure patterns over rectangular sharp-crested weirs.
