Weba) determine the characteristics of flow over a rectangular and a triangular weir, and. b) determine the value of the discharge coefficient for both notches. 4. Method. The coefficients of discharge are determined by … WebTriangular notch or weir is always preferred over a rectangular notch or weir due to the following reasons. The expression for discharge for a right angle V-notch or weir is very simple. Ventilation of triangular notch is not necessary. Triangular notch will provide more precise results during measuring low discharge as compare to result ...

WebDISCHARGE OVER TRIANGULAR-NOTCH THIN-PLATE WEIRS B3 Upstream face of weir plate ^45° FIGURE l.-The triangular-notch, thin-plate weir. energy loss between the measuring section and the weir is negligible. A distance of 4 to 5 h is recommended. BASIC EQUATION OF DISCHARGE The traditional equation of discharge for triangular-notch … Webabove to obtain the discharge over the weir. If q is the discharge per unit width, then q = 2ZH/3 0 udy, and on substituting equation (2) we obtain q = 2ZH/3 0 p U2 +2gH −2gydy … http://irrigation.wsu.edu/Content/Calculators/Water-Measurements/Rectangular-Contracted-Weir.php delaney mitsubishi
