1. Water flows in a rectangular, brick-lined aqueduct of width 1.2 m at a rate of 73,000 m3/day. Determine the water depth if the change in elevation over the 16-km length of this channel is 9.6 m.
2. A rectangular, unfinished concrete channel of 28-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 ft3/s.
