Question
Determine the angle $\theta$ of the channel so that it has the best hydraulic triangular cross section that uses the minimum amount of material for a given discharge.
Step 1
First, we need to define the best hydraulic triangular cross section. The best hydraulic cross section is the one that has the maximum hydraulic efficiency, which is the ratio of the flow area (A) to the wetted perimeter (P). In other words, we want to maximize Show more…

Determine the length of the sides $a$ of the channel in terms of its base $b$, so that for the flow at full depth it provides the best hydraulic cross section that uses the minimum amount of material for a given discharge.
Determine the angle $\theta$ and the length $l$ of its sides so that the channel has the best hydraulic trapezoidal cross section of base $b$.
A drainage channel is to be made so that its cross section is a trapezoid with equally sloping sides (Figure Ex-48). If the sides and bottom all have a length of $5 \mathrm{ft}$, how should the angle $\theta(0 \leq \theta \leq \pi / 2)$ be chosen to yield the greatest cross-sectional area of the channel?
