Question 5 a) Drinking water distribution pipe work data are listed below for the network shown in Fig. Q5. Water storage facilities at nodes 1 and 2 have constant top water levels of 100 m and 75 m respectively above a fixed datum, and the rate at which water is drawn off at nodes 3 and 4 is 250 l/s and 350 l/s respectively. Using Hardy-Cross head balance method (two iterations only), calculate the magnitude and direction of flow in pipe 3-4. Length (m) 1000 Pipe Diameter Hazen-Williams (mm) Coefficient 1-3 750 90 3-4 400 750 110 2-4 600 1000 90 350 /s 250 /s Figure Q5 b) If valve at node 4 is fully closed (i.e., demand at node 4 is zero), how the pressure at node 3 will be affected, explain?
