Chapter 7 – Problem 7.4

7.4 A relatively new 2 km long 300 mm diameter prestressed concrete (PSC) gravity main connects two reservoirs with a water surface elevation difference of 27m. Compute the Hazen-William and Darcy-Weisbach roughness values of the pipeline if the measured flowrate is 0.3 m3/s. A thorough inspection has indicated that there were no air blockages and no additional losses along the pipeline.
