Consider uniform water flow in a wide channel made of unfinished concrete laid on a slope of 0.0019. Now water flows over a 20 -cm-high bump. If the flow over the bump is exactly critical ({Fr}=1), find the flow rate and the flow depth over the bump per meter width.
a. 0.045 m³/s, 0.40 m
b. 0.053 m³/s, 0.30 m
c. 0.060 m³/s, 0.35 m
d. 0.036 m³/s, 0.45 m
