Chapter 0 – Problem 0.4
0.4 Compute the friction headloss in a 6m section of 3m diameter, mild steel pipe carrying water at a velocity of 2 m/s. Use the Darcy-Weisbach equation with a manufacturer-suggested pipe roughness element size of 0.12 mm. What is the associated unit friction headloss (headloss per 1000 m length)? What is the equivalent Hazen-William roughness coefficient?
[Answers: 0.004 m, 0.667 m/km, and 139.22]
