A designed sewer line is made of 535-mm diam n a slope of 0.001 and enters a manhole with a crown elevation of 2.50 m. m3/s. It is expected that an pipe o The (average) design flowrate of the additional flow of 0.02 m3/s will enter at the manhole, and the downstream sewer line leaving sewer line is to be designed for a peak-flow factor of 2.0, a minimum-flow factor of 0.5, and a maximum allowable flow depth equal to 75% of the pipe diameter. If the ground-surface elevation upstream of the new sewer line is 5.00 m, the ground- surface elevation at the manhole downstream of the new sewer line is 4.50 m, and the new sewer line is 150 m long, determine: a. the diameter and slope of the new sewer line
b. the crowa and invert elevations at the upstream and downstream ends of the new sewer line. sewer line is 0.130 the manhole will carry an average flow of 0.15 m^2/s.
