Flow measurement by notched weir

WebThe Cone equation is commonly used for 90degree V-notch weirs. This equation is reliable for small, fully contracted weirs generally encountered in measuring water for irrigation. … WebFor fully contracted V-notch weirs, the value of k h is related to as given on figure 7-6a, and values of C e are read from figure 7-6b. Partially contracted 90-degree V-notches only can be rated using figure 7-7 to obtain C e values. The calibration relationships were developed with rectangular approach flow and head measurement sections for these weirs.
