For each of the channels designed in Problem 14.25, compute the required slope if the channel is float-finished concrete. Plot slope versus bottom width.

In Problem

It is desired to carry 2.00 m³/s of water at a velocity of 3.0 m/s in a rectangular open channel. Compute the depth and hydraulic radius for a range of designs for the channel, with bottom widths of 0.50 m to 2.00 m. Plot depth and hydraulic radius versus bottom width.
