Question 1

What would be maximum possible discharge through a 2.5 m wide rectangular channel, if specific energy for the flow is 1.2 N-m/m

Question 2

A wide rectangular channel has a longitudinal slope of 1 in 2500 and its manning’s roughness has been assessed as 0.024 . If the discharge intensity is 1.8 m³/s/m, then the normal depth of flow in this channel is

Question 3

An earthen channel with a base width of 1.6 m and side slope 1 horizontal to 2 vertical carries water with a depth of 0.80 m. The bed slope is 1 in 750. If n = 0.025, the average shear stresses at the channel boundary is

Question 4

Direction: Each of the following items consists of two statements, one labelled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answers to these items using the codes below:

Statement (I): In pure cohesive soils, the ultimate bearing capacity is independent of foundation width.
Statement (II): The ultimate bearing capacity of pure cohesive soils increases with depth below ground level.

Question 5

The sequent depth ratio of a hydraulic jump in a rectangular channel is 13.65 . What is the Froud’s number at the beginning of the jump

Question 6

Direction: Each of the following items consists of two statements, one labelled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answers to these items using the codes below:

Statement (I): A moving hydraulic jump is called a surge.
Statement (II): The travel of a wave is faster in the upper portion than in the lower portion in case of positive surges.

Question 7

A partially open sluice gate discharges water at 6 m/s with a depth of 40 cm in a rectangular horizontal channel of width 5 m. What would be the post-jump depth of flow on the downstream of the gate by taking g as 10 m/s²?

Question 8

Hydraulic jump forms in a horizontal rectangular channel carrying a unit discharge of 1.019 m³/sec/m at a depth of 101.9 mm.
This jump is classified as
