A) A rectangular channel flowing normally rull at a depth 1.40 m has base of width 2 m. The flow rate is 3.6 m³/s. It is to be replaced by an efficient rectangular section with the same material and adhering to the same slope. (a) What is the increase in its capacity? (b) If instead the most efficient trapezoidal section were used, what would be the increase in the flow rate? (c) What percent increase could have been expected if the most efficient of all efficient sections were used?
