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
