R-9 Hydraulic Network Topology, Nodal Demands, and Pipe Design Options for MATLAB Modeling

The Excel workbook includes: (1) 72 pipes with pipe identifier, length, origin node, and destination node; (2) 61 demand nodes with nodal demand, elevation, and minimum required pressure head; and (3) 10 commercial pipe options with diameter, Hazen-Williams coefficient, and historical unit cost.

The external source or reservoir connected to node 1 is represented by a dash in the first origin record. The data were adapted and reformatted from the R-9 benchmark reported by Surco, Vecchi, and Ravagnani (2018), based on the network previously described by Gomes et al. (2009). They were used as instructional input in a completed engineering education study on the application of graph theory and MATLAB to model engineering systems, automate the construction of incidence matrices and conservation equations, and support project-based learning in hydraulic network analysis.
