Which of the following expression represents the energy dissipated in the hydraulic jump? y, and y, are the flow depth at supercritical flow and subcritical flow respectively.

A

$$ \triangle E=\frac{(y_{2}-y_{1})^{3}}{4y_{1}y_{2}} $$

B

$$ \triangle E=\frac{(y_{2}+y_{1})^{3}}{4y_{1}y_{2}} $$

C

$$ \triangle E=\frac{(y_{2}+y_{1})^{3}}{4\sqrt{y_{1}y_{2}}} $$

D

$$ \triangle E=\frac{(y_{2}-y_{1})^{2}}{4 y_{1}y_{2}} $$
