Water at 68◦ F flows at a discharge of 15 ft3 /sec in a rectangular channel that is 2.5 ft wide, with a channel bottom slope of 0.04 ft/ft, as illustrated in Figure ECP 5.22. The channel length between points 1 and 2 is 3600 ft, and the Chezy coefficient of 150 ft1/2 s −1 . (a) Determine the uniform depth of flow in the channel. (b) Determine the head loss due to channel friction between points 1 and 2
