###### Question details

Water flows at 4.6 m/s and a depth of 0.75 m in a rectangular canal. Find the change in the flow depth produced by

(a) a smooth upward step of 0.15 m, and

(b) a smooth downward step of 0.15 m. Rework the problem for the case where the energy head loss through the transition is equal to about 5% of the velocity head upstream of the step.
