Question

As the specific energy increases for a fixed discharge, the depth of flow

• A. Remain constant
• B. Increases
• C. Can't comment
• D. Decreases

Answer 1

The correct option is C Can't comment


It is clear from graph that,

For $y>y_c,i.e.,$ subcritical flow $\Rightarrow$ E $\uparrow$ y $\uparrow$

For $y{<}_c,..i.e..,$ supercritical flow $\Rightarrow$ E $\uparrow$ y $\downarrow$
