WebNov 25, 2014 · The theoretical discharge equation of a circular thin weir ends up the complete elliptic integrals of the first and second kinds that are not very suitable for practical purposes due to their ... WebUsing the water surface elevation and the weir dimensions, equation 4.4 can be used to estimate the discharge for a 90° V-notch compound weir, as performed in example 4.3. A circular weir also measures both small and large discharge but is less accurate at large discharge than the other methods listed in table 4.2. Links: top, bottom. When ...
How to Calculate and Solve for Weir Discharge - Nickzom Blog
WebDetermine the weir loading rate: Example: A circular clarifier receives a flow of 4.25 MGD. If the diameter of the weir is 100 ft, what is the weir loading rate, in gpm/ft? To determine the feet of weir, use the formula: π x Diameter. Weir length, ft = π x Diameter. Weir length, ft = π x 100 ft. Weir length = 314 ft . Convert flow from MGD ... WebBroad-crested or suppressed weir: no air gap exists between downstream side of weir and water flowing over the weir Example • A circular clarifier has D =30 ft and processes 0.5 MGD. An effluent weir with 90o V-notches at 1.0-ft intervals is located 1.5 ft inside the clarifier circumference. How high above the weir crest is the water in the ... how to stick with weight loss
