Question: 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

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.
