PHO Two reservoirs A and B is connected by a 250 mm dia. pipe which is 1000 m hng. Reservoir B is 8 meters below that of A. Another reservoirs C and D is also connected by a 300 mm pipe, 2200 m. long with reservoir D 10 m. below that of C and reservoir C is also 4 m below that of A. In order to increase the quantity. of water entering reservoir D, the two pipelines AB and CD are connected by a pipeline EF which is 1800 m. long which branches from the 250 mm o at a point E 400 meters from A and connects with the 300 mm pipe at F 800 meters from reservoir D. a) Determine the quantity of water flowing towards B and D if 25 liters • per second flow through pipe EF. Assume friction factor f to be 0.02 for all pipes. Consider only friction losses. b) Determine also the diameter of the pipe EF to carry 25 liters/sec.
