WebFigure 1: Side view of sharp-crested weir Consider the flow problem as shown in Figure 1, which in this se ction we will consider to be two-dimensional only, where a weir extends the whole width of the (rectangular) channel. A uniform flow of discharge q per unit width and depth d encounters the sharp-edged weir, whose crest at C is of height Weballowing the weir tank to drain to the respective level of the crest. Subtracting the crest elevation from that of the water-surface elevation during the tests upstream of the v-notch weir gives the head on the weir in feet of water.
