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

This dataset contains the tabular input data used for graph-based modeling and optimization of the R-9 water distribution network in MATLAB. 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. The workbook contains input data only. It does not contain student information, personal data, simulation outputs, or optimization results. The unit costs are historical benchmark values and should not be interpreted as current market prices.
