For strong Hydraulic jump containing maximum energy, the down stream glacis should be sloped at a slope of ______________ to dissipate max: energy?
Correct answer: C. 3:1 to 5:1
- A. 2:1 to 2.5:1
- B. 2.5:1 to 3:1
- C. 3:1 to 5:1
- D. 5:1 to 6
Explanation
A downstream glacis slope of about 3:1 to 5:1 promotes a strong hydraulic jump and effective energy dissipation in the stilling basin. Flatter or steeper ranges do not represent the standard range used for this purpose.
