WebV notch weirs really are just that a thin plate weir with a ‘V’ notch cut into it. The weir is placed to obstruct open channel flow and allow water to flow over the notch. This enables us to accurately measure the flow, by measuring the head upstream of the V notch. WebWeirs (e.g., V-notch, rectangular, circular, compound): As fluid passes over a weir, it transitions through critical flow (Froude number = 1) to super-critical (Froude number > 1). Discharge at critical flow is solely dependent on the cross section. desk mounted microphone boom armWebDischarge values for Cipolletti weir notch lengths of up to 4 feet and depths of flow up to 1.5 feet are given in Table 2 . 90° V-Notch Weir The 90° V-notch weir, Figure 5 , is most accurate when measuring discharges of less than 500 gpm.
