For a wide rectangular channel using Manning’s formula, the differential equation of gradually varied flow (with the usual notations) is given by
The stage in a river is 4.8 m, the water surface slope is 1 in 10,000 and the discharge in the stream is 600 m^{3}/s. If the stage remains the same and the water surface slope is 1 in 14,400, then the discharge in the stream will be
Water surface profiles that are asymptotic at one end and terminated at the other end would include
For a hydraulically efficient rectangular section, the ratio of width to normal depth is
Consider the following statements in regard to the critical flow:
1. Specific energy is maximum for a given discharge.
2. Specific force is maximum for a given discharge
3. Discharge is maximum for a given specific force.
4. Discharge is maximum for a given specific energy.
Which of these statements are correct?
If F_{1} and F_{2} are the Froude numbers of flow before and after the hydraulic jump occurring in a rectangular channel, then
The momentum correction factor for a flow through open channel is given by
The Froude number of a hydraulic jump is 5.5. The jump can be classified as a/an
A hydraulically efficient trapezoidal section of open channel flow carries water at the optimal depth of 0.6 m. Chezy coefficient is 75 and bed slope is 1 in 250. What is the discharge through the channel?
