Given the data below, design a section of sanitary sewer to carry these flows at minimum velocity of 2.5 fps. Assume that the minimum depth of the sewer below the street must be 8.5 ft and that an n value of 0.013 is applicable. Make a plan and profile drawing. ( Note: the invert into Manhole F must be 937 ft. Assume an invert drop of 0.2 ft across each manhole. ) Manholes (M) Distance between M (ft) Flow (gmp) Street elevations at M (ft) A-B 180 1200 A- 978 B-C 300 1450 B- 972 C-D 450 2200 C- 964 D-E 300 2500 D- 958 E-F 400 3000 E- 954 F- 949
