When the weir becomes drowned, the Reynolds and Weber numbers vis-à-vis Eq. (10.61). If flow rate decreases by the following factor: not, suggest another correlation. | v v P10.120 The rectangular channel in Fig. P10.120 contains a Vnotch weir as shown. The intent is to meter flow rates between 2.0 and 6.0 m3/s with an upstream hook gage set to measure water depths between 2.0 and 2.75 m. What are the most appropriate values for the notch height Y and the notc...
