Question

The percentage of energy dissipation in a hydraulic jump increases with the increase in the Froude number.

(a) True

(b) False

The question was posed to me during an internship interview.

I would like to ask this question from Energy Dissipation Below Overflow Spillway topic in division Spillways, Energy Dissipators and Spillway Gates of Irrigation Engineering

Answer 1

Right answer is (a) True

To explain I would say: The energy dissipation in the jump depends upon the Froude number, if this Froude number is higher, the greater energy dissipation can take place.
