2 X. In general, open-channel flow operates in regime . Hydraulic jump occurs when the flow suddenly changes from up100 are used to measure flow in small rivers and canals 2 4. For uniform open channel flow when maximu m discharges desired, the channel geometry should have wetted perimeter 5. The specific energy is the sum of the and energies &If; the velocity profile of the open channel remains constant over time it is called If the velocity profile of the open channel flow is same in all locations it is called V8. The drag coefficient CD is a number 9?9 The steady uniform flow along a sloped channel can be calculated using equation 2 10. The steady uniform open-channel flow occurs when the channel has 111. The flow or discharge over a weir can be calculates usingequation 2. The channel shape when flowing fully is most efficient for open channel flow Semi-circular Potential f-I Kinetic D Critical Sub-critical Super-critical Q Bernoulli ? 1 Manning Laminar Weirs L Unsteady I Steady Uniform Dimensionless P Minimum Constant

Explanation / Answer

1. Option L is correct

because velocity of open channel isn't constant with time

4. Option A is correct

because Semi circular channel will discharge more water than any other chanel

9. Option H is correct

Because Manning equation is used for open channel flow

10 -Option q is correct

11. Option G is correct
