Problem 2
Size the channel for a mechanically cleaned coarse bar rack for a flowrate of 40,000m3d. The bar rack will be set at an angle of 75 degrees from horizontal and will have clear bar spacing of 12mm. The bar rack uses 12-mm-wide by 25-mm deep bars. The upstream channel velocity should be greater than 0.4ms. Determine the headloss through the bar rack for the clean screen and for a screen that is 50 percent clogged.
