Flow over v notch weir
WebV-notch weirs are a common method for estimation of discharge flow rate in the field. They comprise a thin plate weir where the area of flow is a notch cut in the shape of a ‘V’ with an internal angle of a (see Figure A6.1), normally installed in a tank. The flow rate over the weir is a function of the head over the weir, the size and shape of the discharge area, … Webmust flow over and is used as an indirect method for obtaining the flow rate based on the weir geometry and head over the weir crest. The sharp crested weir was widely used to compute the flow discharge (M. Piratheepan et al., 2006). The sharp crested were divided into three types which are rectangular weir, V-notch weir and trapezoidal weir.
