Question-1 (30p): The following waste water collection system is given below with the length of the channels, areas that served by each channel and their population intensities. A constant discharge with 25 l/s is added to the system from manhole 2. a) According to given information, design the channels using Kutter Formula (m=0.35). Assume 24 hours water usage is removed in 16 hours through the sewage system. _Available pipe diameters: 300, 400, 500, 600....mm, maxqday= 200 lt/day/capita, (h/D)max=%90, b) Explain why the waste water conduits is not allowable to be flowed completely full or pressured. 100R 1 (40) (41) (41) Pipe Lenght(m) Area(ha) N(capita/ha) 50 1.5 400 2.5 (44) 500 Q = 251/s V = SRJ m+ VR 1-3 200 2-3 3-4 40 60 2 2
