Flow over v notch weir

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. http://xmpp.3m.com/flow+over+a+weir+lab+report

The edge or surface over which the water flows is called the crest. The overflowing sheet of water is the nappe. If the nappe discharges into the air, the weir has free discharge. If the discharge is partly under water, the weir is submerged or drowned. phoenix high school gwinnett

WebCivil Engineering questions and answers. Determine the maximum possible flow rate over a 60degree V-notch weir if the width of the notch at the top is 12 inch. (C_d = 0.578). Maximum flow will occur when the water-level reaches the top of the weir. WebV notch weirs really are just that a thin plate weir with a ‘V’ notch cut into it. The weir is placed to obstruct open channel flow and allow water to flow over the notch. This enables us to accurately measure the flow, by measuring the head upstream of the V notch.
