A rectangular concrete channel (n = 0.015) has a bottom width of 10.0 m and a discharge rate of 43 m/s. Plot the specific energy diagram for depths ranging from 0.5 m to 3.1 m. From the diagram, determine (a) critical depth, (b) minimum specific energy, (c) specific energy for a water depth of 0.8 m, and (d) water depths when the specific energy is 2.7 m. What channel slope would result in critical flow?
