Water flows in a rectangular channel with a flowrate per unit width of \(q=1.5 \mathrm{~m}^{2} / \mathrm{s}\) and a depth of \(0.5 \mathrm{~m}\) at section (1). The head loss between sections (1) and (2) is \(0.03 \mathrm{~m}\). Plot the specific energy diagram for this flow and locate states (1) and (2) on this diagram. Is it possible to have a head loss of \(0.06 \mathrm{~m}\) ? Explain.
