Question: a 10 ft high sharp crested weir with cd ...
- A 10 ft high sharp crested weir with cd = 0.63 was constructed across the same channel given in previous question. For the above flow condition, what is the expected depth weir?
(I am referring to the last question in HW 1:
In a channel, flow is taking place with a velocity of 1.2 ft/s with a normal flow depth of 8.5 ft. The channel is a rectangular section with a width of 20 ft. Find the following:
- Find Q (ft3/s)
- Specific energy head in ft
- Hydraulic mean radius R in ft
- Froude number
- Decide whether it is a sub critical flow or super critical flow
- Find the critical depth)
