Consider a rectangular channel that is $10$ meters wide. Plot the specific energy curve for flow rates

of $2\frac{m^3}{s},4\frac{m^3}{s},$ and $6\frac{m^3}{s}$ on one figure. Please see note above regarding plots and tables. The

abscissa should include the specific energy $($E$)$ and the ordinate should display the flow depth.

Please use the same scaling $($range and spacing$)$ for both axes. Appropriately label the supercritical

and subcritical "branches" of one of the curves.
