Question
A hydraulic jump is formed in a 5 m wide rectangular channel, which has a horizontal bed and is carrying a discharge of 15 m/s. The depth of water upstream of the jump is 0.5 m. The power dissipated by the jump (in kW) is ___________ (rounded off to the nearest integer).Note:
Acceleration due to gravity = 9.81 m/s
Density of water = 1000 kg/m
Kinetic energy correction factor = 1.0
Acceleration due to gravity = 9.81 m/s
Density of water = 1000 kg/m
Kinetic energy correction factor = 1.0
Correct answer
69 to 75
Solution
1.Calculate discharge per unit width ():
2.Calculate the Froude number upstream ():
3.Calculate the sequent depth ():
4.Calculate the head loss ():
5.Calculate the power dissipated ():
Rounding to the nearest integer, the power dissipated is 72 kW.Continue learning with Success Tracker
