A trapezoidal flume carries water. It has a base of 30 cm, a top of 60 cm, and sloped wall lengths of 25 cm. The water flowing in the flume has a vertical depth of 16 cm with a wetted perimeter of 70 cm. The flume has a Manning roughness coefficient of 0.02 and a slope of 10 m/km. The total flume area is 900 cm2, while the flow area is 672 cm2. Using the Manning equation for open channel flow, what is most nearly the velocity in the flume in m/s
