Resumo
The hydraulic analysis tools are important in the performance
evaluation of water distribution networks. Various methods
are available for such analysis. However, the hydraulic models
that solve the system of equations describing the flow problem
through Newton-Raphson or through its successive linearizations
are the most efficient. It is the purpose of this paper to compare
Newton-Raphson, Linear Theory, Hybrid and Gradient methods
for steady-state hydraulic network analysis, considering leakage
and pressure driven demand modeling. The network layout
with hydraulic components frequently used in the literature was
employed for this analysis. The Gradient method was found to
produce best results in terms of number of iterations for the more
simple networks, whereas the Hybrid method was better for more
complex networks.
