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.

WebB (m) is the width of the contracted notch (rectangular), or the width of the channel (suppressed) g is the acceleration of gravity (9.81 m/s²) Sharp-Crested Weir V-Notch (Triangular) Used in cases of small discharge Best weir to measure discharge in an open channel Highest accuracy when measuring flow rate (usually +/-2%) WebMar 8, 2024 · The study site was monitored for a two-year period between October 2011 and September 2013. Flow was measured hourly at two 45° v-notch weirs with stage height measured by a Unidata Hydrologger water level recorder (1 mm resolution; Unidata Pty, O’Connor, WA, Australia) and converted to flow using a theoretical rating equation. Web1. A weir can be used to measure flow rate, from the known relationship between height of the water level above the weir crest, weir length and flow rate (assuming the water level downstream is below the weir crest). … irish monologues for men
