Question: Water flows through a rectangular channel with a width of 1 0 ft . The water depth in the channel is 5 ft and the

Water flows through a rectangular channel with a width of 10 ft. The water depth in the channel is 5 ft and the flow rate is measured to be 3 ft/S. If a small rectangular channel is designed to change the flow under conditions that do not affect the upstream flow (the condition that no choke occurs), what will be the minimum floor width? Ignore the incidental losses.
