Three pipelines run in parallel from Station A to Station B to deliver water at a rate of 450 L/s as part of a larger water distribution network. Details of the three pipelines are provided below in Table 2. Determine the headloss between Stations A and B using the Moody diagram and the Darcy-Weisbach equation. Include a clearly marked Moody diagram for each pipe in your solution, showing Re and k/D for each f as used in your
calculations of friction headloss with the Darcy-Weisbach equation. Complete at least two iterations in your solution.
