In the present work, a survey of some of the many published evaluations of these methods was first conducted, and then, additional detailed comparisons with elastic-plastic finite element analyses for a series of semicircular and V-shaped notch configurations were performed. Two of the most widely used approximations for this response are Neuber's rule and Glinka's equivalent strain energy density method. Step 2: Write the formula and enter the values.It is widely recognized that the accuracy of notch fatigue calculations can be improved significantly when those calculations are based on the elastic-plastic response strain at the notch root, as opposed to the remotely applied loads or stresses. What will be the flow rate if the discharge constant is 8?

Q stands for flow rate or discharge rateĪ v-notch of angle 35 degrees and head as 15 was installed on a canal.

The formula used for a fully contracted weir notch is: The triangular notch changes the depth of water discharging, providing more accuracy.Ī fully contracted weir is one that has H < 2b (b is the distance of the weir from both sides). The measurement is taken by the principal that discharge is directly related to the head of the weir. It is used because of the accuracy in head measurements it provides. What is a V-notch weir?įlow rates of streams and canals are determined usually by installing a weir.Ī V-notch is a triangular weir that has become the standardized weir over time of period. This calculator is used to calculate the discharge of a fully contracted weir flow. This V Notch calculator computes the flow rate of a triangular weir using the values of its hydraulic head and notch angle.
