ABSTRACT
The HGM (Hydraulic Gradient Method), it is used in most of the current
commercial software, such as EPANET, WaterCAD, MikeNet, among others, the same
that corresponds to an iterative method that depends on initial estimated
parameters and programming structures that ensure convergence to obtain results
with the highest precision, in addition to this the method makes use of
non-linear equation systems. Likewise, the execution time for large extensions
of water distribution networks is considerably high. On the other hand, the PM (Perturbation Method), is a new direct
solution method, which makes use of principles of quantum mechanics to
transform nonlinear equations into simpler linear systems. Obtaining a simple
and robust optimization method that only requires simple and direct
mathematical processes. Using the MathCad and
Python programming languages as a verification tool, multiple tests were
carried out, the results for the hydraulic parameters showing that the flow
rates and pressures obtained by the HGM and the PM are extremely similar, in
the same way the execution time (time run) have been 77.09% favorable to the
PM. In other words, the PM presents efficiency to estimate the hydraulic
characteristics such as the pressures at the nodes and the velocities in the
pipes of the drinking water distribution networks.
