Question Paper
Derive the basic equation of continuity for unsteady open channel flow in the following form:
<img src='./qimages/9548-1a.jpg'> A trapezoidal channel carries a discharge of 7·1 m^3/sec. If the bottom width of the channel is 3 side slope is 1.5 1 and longitudinal slope is 0.0016, calculate the depth of flow. The value of Manning's Roughness coefficient is 0·13.
2.(a) Derive the equation governing the critical flow condition for constant discharge situation.
Calculate the critical depth and the corresponding specific energy for the discharge of 5·0 m^3/sec in a rectangular channel of bottom width 2·0 m.
3.(a) Derive the basic differential equation of Gradually Varied Flow in the following form:
<img src='./qimages/9548-3a.jpg'>
where
So =bed slope
Sf =slope of energy line
Q= discharge
A cross-sectional area
a kinetic energy correction factor
T =top width of the channel
For the compound channel shown in the figure, determine the discharge for the depth of flow of 1·2 m. Use partial area discharge method. Assume n =0·02 and S0 =0·0002. <img src='./qimages/9548-3b.jpg'>
4. A discharge of 16.0 m^3/sec flows with a depth of 2·0 m in a rectangular channel which is 4.0 m wide. At a downstream section, the width is reduced to 3.5 m and the channel bed is raised by liZ. Analyse the water surface elevations in the transition, if liZ =0·20 m.
5.(a) Derive the equation for normal depth in a wide rectangular channel.
Discuss the mechanics of surges. Also derive the equation for the wave velocity.
6. A rectangular channel carries a flow at a depth of 2·5 m with the velocity of 2·0.m/sec. The flow is suddenly quadrupled, due to an urgent requirement on the downstream side, by an abrupt opening of a head gate. What will be the type of resulting surge Determine the final depth of flow, height of the surge, clarity wave speed and overrun.
7.(a) Discuss the various wave parameters. Also list the assumptions of first order wave theory. Classify the water waves based on the relative depth. Also discuss the characteristics of each wave type.
8. List the assumptions for the uniformly progressive flow in open channel. Derive the dynamic equation of uniformly progressive flow in open channel in the following form <img src='./qimages/9548-8.jpg'>
