Appendix 0 – Problem 60
A0.60 Compute and tabulate unit friction headlosses (headloss per 1000m of pipe) for pipelines with the range of diameters shown in the following table. The flow velocity in each pipeline is 2.2 m/s (generally accepted maximum value in water pipeline systems). Assume that each pipeline is 2500m long. Use either Darcy-Weisbach equation (with a roughness element size of 0.15 mm for all pipe sizes) or Hazen-William equation (with a roughness coefficient of 130 for all pipe sizes).
