Unformatted text preview: Fill out the following influence chart: Influence Chart Increase in this Parameter Effect on Normal Depth Effect on Froude Number Q S b Manning’s n Problem 2: You are asked to design a rectangular channel. The discharge is 50 ft 3 /s, slope is 0.01 ft/ft, Manning’s n is 0.02 (i.e. like in Problem 1 above.) Your design is defined as most efficient if the cross-sectional area is minimized. What channel width, “ b ”, will produce the most efficient channel for these conditions?...
