A rectangular open channel having a hydraulic radius of 0.25 m, is laid at a slope of 1 in 1000. If the depth of flow is equal to half the bottom width of the channel, the depth of flow (y) and bottom width (B) of the channel for the flow condition are:
- 1y = 0.2 m; B = 0.4 m
- 2y = 0.5 m; B = 1 m✓
- 3y = 0.25 m; B = 0.5 m
- 4y = 0.4 m; B = 0.8 m
Correct answer
y = 0.5 m; B = 1 m
