11. A discharge of 2.5 m3 /s is to be carried in a rectangular
channel (𝑛 = 0.02). It is desired to maintain a velocity of 1.3
m/s. Find the most economical dimensions and the slope
required.
12. The depth of flow in a trapezoidal channel is to be
restricted to 1.5 m. If the section is to be most efficient, find
the slope required to carry a discharge of 15 m3 /s. The side
slopes are 11 2 ; H: 1 V and 𝑛 = 0.015
