In designing a canal for supplying a power plant, the problem arises as to whether a trapezoidal or rectangular section should be built. If the former be used, it is found that, with a clean earth lining, a flow section with a top width of 12.20 m, bottom width of 3 m, and water depth of 1.50 m, will deliver the required quantity of water if laid on a slope of 0.00075. Could a lesser slope be used employing a rectangular section if the area of flow and velocity were maintained at the same values as in the trapezoidal section? What would be its value? (Use n = 0.020 for both sections).
