Hydraulics: Flow Networks -Concept and Example

16. Two-pipes, each 300 m long, are connected in series. Water flow through pipes is 150 lit/sec with a total frictional loss of 15m. If one pipe has a diameter of 300 mm. Neglect the minor losses. What is the Diameter of the other pipe if f = 0.02 for both pipes? a. 245 mm c. 255 mm b. 250 mm d. 260 mm Situation 6: Given the following data for three pipes in parallel: Pipe 1: D1 = 450 mm, L1 = 800 mm Pipe 2: D2 = 400 mm, L2 = 700 mm Pipe 3: D3 = 500 mm, L3 = 600 mm The total flow is 0.86 m3/s. Assuming f = 0.02 for all pipes, evaluate the following: 17. The flow in pipe 1 in m3/s a. 0.208 m3/s c. 0.392 m3/s b. 0.261 m3/s d. 0.356 m3/s 18. The flow in pipe 2 in m3/s a. 0.261 m3/s c. 0.208 m3/s b. 0.356 m3/s d. 0.356 m3/s 19. The flow in pipe 3 in m3/s a. 0.392 m3/s c. 0.261 m3/s b. 0.208 m3/s d. 0.356 m3/s
