Using the Manning nomograph and assuming n=0.013, determine the following: (a) An 800 mm diameter sanitary sewer is built on a slope of 0.2 percent. What is the fullflow discharge capacity of the sewer and what is the flow velocity? (b) What diameter pipe is needed to carry a peak flow of 200 liters/s on a grade of 0.007 ?

Given the data below, design a section of sanitary sewer to carry these flows at a minimum velocity of 2.5 fps. Assume that the minimum depth of the sewer below the street must be 8.5ft and that an n value of 0.013 is applicable. Sketch a profile drawing. (Note: The invert into manhole F must be 937 ft. Assume an invert drop of 0.2 ft across each manhole regardless of possible sewer diameter changes at each manhole, i.e., sewer pipes would not be connected crown-to-crown.) Assume that 8, 10, 12, 15, 18, 21-inch diameter pipes are commercially available.
