A rectangular, unfinished concrete channel of 38-ft width is laid on a slope of 8 ft/mi. Determine the flow depth and Froude number of the flow if the flowrate is 400 ft^3/s. a) Flow depth = 4.64 ft, Froude number = 0.66 b) Flow depth = 5.28 ft, Froude number = 0.72 c) Flow depth = 4.64 ft, Froude number = 0.72 d) Flow depth = 5.28 ft, Froude number = 0.66
