2021-2022 SUMMER Question 3 (25p): Reservoir A is feeding the reservoirs B and C. The discharge in pipe AD is 0.17 m/s. The elevation heads of D and E are 65 m and 60 m, respectively. Friction factor for all the pipes is =0.03. Determine; a) The elevation head of the Reservoir B. b) Pieozometric heights of point D and E. c) Pressure heads of point D and E. d) Draw the energy grade line of the system. by ignoring the minor head losses and assuming that the water levels in the reservoirs are constant. 100 m A D 1 2 3 84 m C 148 B Pipe AD DEI DE2 DE3 EC EB L (m) 500 1000 2000 1000 800 600 D (mm) 400 300 300 300 200 250
