A trapezoidal ditch is designed with a bottom width of 3 space f t and side slopes of m equals 1 on both sides. The channel is made of concrete (n equals 0.013) and has a longitudinal slope of 1 percent sign. If the flow rate on a particular day is 125 space f t cubed divided by s, determine the depth of flow in the channel. Assume steady uniform flow.
