A channel cross section, commonly known as gutter, forms at the side of a street next to a curb during rainfall conditions as shown in the figure. The slope along the roadway is S = 0.001, and the manning roughness coefficient, n = 0.015. Assuming that uniform flow conditions occur, determine the following: a. The discharge (in liters per second) if the depth of flow y = 15 cm. b. If Q 100 liters per sec, what is the depth in mm? c. Ilustrate each figure as specified in sub-sets a and b?
10 In a channel of rectangular cross section with a slope of 1 in 1000, the discharge is to be 1,4 m³/s when the channel is running full. Its depth is half as its breadth. If the channel is roughly excavated, the coefficient of discharge C is 27 in SI units, and the Chezy formula is V = C √(Rs). If the bottom and side slopes are finished smoothly, C = 81 (R = hydraulic radius, s = slope) Assuming the cost of excavation /m³ is twice the cost of smooth finishing /m² Compare the costs of the two types of channels.
