A flood occurs in the main channel having a trapezoidal section with a base width of 4.5 m. If the channel is designed to carry a mean velocity of 1.2 m/s, compute the discharge capacity of the canal in m^3/s using the following conditions: When one side of the canal is vertical and the other sloping at an angle of 45 to the power of 0.The depth is 3/4 of the base width. Choices: A.) 33.41 B.)13.16 C.)31.56 D.)18.34 E.)25.06 F.)50.32 2. When canal has a most economical trapezoidal section. Choices: A.) 33.41 B.)13.16 C.)31.56 D.)18.34 E.)25.06 F.)50.32 3. When the canal is designed for minimum seepage. The sides of the trapezoidal canal slopes an angle of 60 . For min: seepage: b = 4dtan (theta/2) Choices: A.) 33.41 B.)13.16 C.)31.56 D.)18.34 E.)25.06 F.)50.32
