Abstract

Hydraulic characterization of pipe network subject to stochastic water demands S. G. ~uchber~er', Z. ~ i ' & V. G. ~zatchkov~ ' ~ e ~ a r t m e n t of Civil and Environmental Engineering, University of Cincinnati, USA 2 Institute Mexicano de Tecnologia del Agua, Mexico Abstract The Poisson Rectangular Pulse process is used to generate residential water demands with an ultra-fine time resolution (one second) over a 55-hour period at all 138 nodes in a real all-pipes municipal water distribution network. The network equations are then solved with an ad hoc solver to generate unsteady instantaneous rates of flow in each pipe. This computational approach provides an unprecedented level of detail and affords new insights in the analysis of municipal pipe networks. Simulation results include the frequency of stagnant, laminar, transition and turbulent flow, the number of flow direction reversals, the coefficient of variation of the flow rate, the minimum and maximum rates of flow and other hydraulic
