WebIn regards of the rectangular weir, the experimental discharge coefficients over the five trials are: 0, 0, 0, 1, 0. Its theoretical constant is usually 0. While looking at triangular weirs its experimental discharge coefficients for the five trials came out to be: 0, 0, 0, 0, 0. With a typical theoretical constant ranging from 0 - 0. WebAs shown in table 4.2 and figure 4.2, the compound weir composed of a 3-inch 90° V-notch section and a 5-foot rectangular section (see figure 4.4) measures small discharge as accurately as a 90° V-notch weir but also measures large discharge without large head requirements (e.g., 14 cfs with less than 1.0 ft of head over the weir).
