Size pipe diameters for lay-out shown in the figure, if the maximum allowed hydraulic gradient Smax=0.005. Determine the surface level of the reservoir at supply point, which maintain the minimum pressure 20 mwc. Assume C=120 for all pipes. 5 Node Z (ms) Q (Us) Node Z (msl) Q (Us) 1 17.6 5.0 6 18.0 3.8 2 18.2 7.6 7 16.5 4.4 3 16.0 9.9 8 19.0 10.5 4 21,4 3.5 9 20.4 9.2 10 22.7 4.2 4 700 420 380 470 3 2 800 5 300 6 450 8 330 9 265 Nodes: D Pipes: L{m) 7 10
