Chapter 2 – Problem 2.4
2.4 In a typical drinking water distribution network model, a pipe element is defined as any section of the pipeline between two node elements (junctions, pumps, valves, tanks, reservoirs, etc.) which has the same physical characteristics (diameter, material, and roughness) and uniform flowrate throughout its length.
Review any carefully built water distribution network model (that includes pipe elements within the pump stations modeled as close to reality as possible) that you have access to. What percentage of pipe elements in the network model are (a) shorter than 1m, (b) shorter than 5m, (c) shorter than 100m, (d) longer than 500m?
