Answer:
Super critical
1.2 m
Explanation:
Q = Flow rate =
w = Width = 3 m
d = Depth = 90 cm = 0.9 m
A = Area = wd
v = Velocity
g = Acceleration due to gravity =
Froude number is given by
Since the flow is super critical.
Flow is critical when
Depth is given by
The depth of the channel will be 1.2 m for critical flow.
