Question

In a hydraulic jump taking place in a horizontal rectangular channel, the sequent depths are 0.30 m and 1.20 m respectively. The energy loss (in m) in this jump will be _________.

• A. 0.506

Answer 1

The correct option is A 0.506
Given:

$y_1=0.3m,y_2=1.2m$

$E_L=\frac{{(y_2-y_1)}^3}{4y_1{y}_2}$

$=\frac{{(1.2-0.3)}^3}{4\times 0.3\times 1.2}$

$=0.506m$
