Screen approach velocity
WebApproach velocity: This design concept is based upon a measurement of the velocity at a prescribed distance from the screen surface, commonly established around 3” or so. … WebDesign information from WEF: Recommended approach velocity between 0.6 and 1.2 m/s Minimum velocity of 0.4 m/s. Construct at least two channels to allow for maintenance. The screen manufacturer provided the following requirements: Channel depth of 0.5 to 4.5 Q_avg = 35,000 m^3/day and Q_peak = 70,000 m^3/day Show transcribed image text
