Water is flowing in a rectangular channel that has a width b1 = 3 m with a depth y1 = 5 m. Then the channel width expanded to b2 = 4 m with a depth y2. If the channel flow has a Froud Number NF = 0.12, which of the following is true about y2. O A. Not enough information is provided to find out OB. y2 is larger than y1 C. y2 is less than y1 OD. y2 = 0.12 m
