Question

At a particular point in the channel, the specific energy and velocity of flow are given by 1.5 m- kg/kg and 2.5m/s respectively. What is the depth of flow in the channel at the point?

• A. 0.5
• B. 2.32
• C. 1.18
• D. 2.5

Answer 1

The correct option is C 1.18

$\therefore E=y+\frac{v^2}{2g}$
$1.5=y+\frac{(2.5{)}^2}{(2\times 9.81)}$
$\because y=1.18m$
$\text{Hence, the depth of flow (y)}=1.18m.$
