Marks: +1, -0

Which of the following expression represents the energy dissipated in the hydraulic jump?

y_ 1

and

y_ 2

are the flow depth at supercritical flow and subcritical flow respectively.

Solution:

Energy dissipated in the hydraulic jump represents as-

∆E = (y_2 – y_1)^3/(4y_1y_2)

; where

y_1

and

y_2

are the flow depths at super critical and subcritical flow respectively.
