Question

- Uniform flow in a channel is characterized by which of the following statements:

Total energy remains constant along the channel

Gradient of total energy is parallel to the channel bed

Specific energy decreases along the channel

Total energy line either rises or falls depending upon the Fr number

- The term alternate depths is used to designate the depths:

at the beginning and end of a hydraulic jump

having the same kinetic energy for a given discharge

having the same specific energy for a given discharge

at the beginning and end of a gradually varied flow profile

- For a given discharge in a channel, the critical depth is a function of

the slope of the channel

the roughness of the channel

geometry of the channel

- If a bridge acts as a choke, the upstream and downstream flow depths of the adjusted flow are

alternate depths

conjugate depths

normal depth

critical depth

Answer 1

Question 1) option 2 is correct ie in uniform flow bed slope ,water surface slope and energy line slope are equal .

Question 2) option 3 is correct

Alternate depths are defined as the depth at same specific energy for a given discharge

Question 3) option 3 is correct ie critical depth is function of geometry of channel like width,depth apart from geometry critical depth also depends on discharge

Question 4)option 2 is correct

Is bridge acts as a choke then upstream and downstream depths are called conjugate depths as hydraulic jump acts at this place
