Question 1

A sluice across a channel 7.2m wide discharges a stream 1.2m deep. Depth upstream of sluice is 7.2m. On downstream side concrete blocks have been placed to create condition for the hydraulic jump to occur. Calculate the force (in kN) on sluice gate. Velocity upstream of sluice is 1.72m/s.

Question 2

If the depth of flow is greater than the critical depth then what can be said about the type of flow

Question 3

In a horizontal rectangular channel, a hydraulic jump with a sequent depth ratio of 5.0 is formed. This jump can be classified as

Question 4

A rectangular channel is conveying 2.8 m3/s discharge. If the % error in measuring head is 2% then the % error in discharge is

Question 5

A rectangular channel of width 4m is carrying a discharge of 36m3/sec. If the depth of flow of one end of hydraulic jump is 1.2m then what is the power dissipated in the jump?
