Abstract: It is good accurately a frequency domain methode or was known too as a Lumped Parameter System (LPS) methode could be applied when the signals response quantity fluctuation (pressure and mass flow rate) as practically (measurement acquitition evidence) have small gain. Referring to that this researh would be given to investigate the mean fluctuation energy flux net different and the power gain stability of hidraulic flow steady state-low Reynold number turbulent in a horizontal pipeline. In this matter, the fluid lines plant could be regarded as an open loop system for which as a fixed parameter of this research, a logingitudinal grooves number variation are seting around of the pipelines profile tangential inner in a fractal geometry imaging. Inverse with laminar flow, there are a primary empirical considering where the turbulent fluid flows hold the LPS modeling because the fluid friction coefficient have small relative change in the relation with the contribution of the small mass flow rate fluctuation.
