Water is flowing in a rectangular channel that has a width b = 3 m with a depth y = 5 m. Then the channel width expanded to b2 - 4 m with a depth y2. If the channel flow has a Froud Number Ne -0.86, which of the following is true about yx O A. Not enough information is provided to find out O B. y2 = 0.86 m OC. y2 is less than yi OD. y2 is larger than y1
