Appendix 0 – Problem 34

A0.34 Compute the friction headloss in a 6m section of 3m diameter mild steel pipe carrying water at a velocity of 2 m/s. Use Darcy-Weisbach equation with the manufacturer suggested pipe roughness element size of 0.12 mm. What is the associated unit friction headloss (headloss per 1000m length)? What is the equivalent Hazen-William roughness coefficient? [Answers: 0.004m, 0.667m, and 139.22]
