Question
A 4 m wide rectangular channel, having bed slope of 0.001 carries a discharge of . Considering Manning's roughness coefficient and , the category of the channel slope is
Correct answer
(B) mild
Solution
1.Calculate critical depth :
2.Calculate normal depth using Manning's equation:
Solving for gives .
3.Compare and :
Since (), the flow is subcritical and the slope is mild.Continue learning with Success Tracker
