Water flows in a horizontal rectangular channel with a flowrate per unit width of \(q=10 \mathrm{ft}^{2} / \mathrm{s}\) and a depth of \(1.0 \mathrm{ft}\) at the downstream section (2). The head loss between section (1) upstream and section (2) is \(0.2 \mathrm{ft}\). Plot the specific energy diagram for this flow and locate states (1) and (2) on this diagram.
