Leakage Modeling Through Empirical Equations: An Experimental Approach

Introduction

Leakage modeling through empirical equations: an experimental approach. Experimentally model water leakage in pressurized pipe networks using empirical equations. Discover significant errors with fixed coefficients and propose a new, more accurate empirical relationship.

Abstract

In this study, an alternative laboratory experimental approach was used to simulate leakage through round shape orifices in a complex pressurized pipe network. In order to achieve a good representation of leakage in water distribution systems, the laboratory network was supplied by centrifugal hydraulic pumps and the leaks were submerged in water during the experiments. The experimental data was used to investigate common relationships to model leakage flow according to system pressures. The results pointed to the existence of significant errors when fixed coefficients are adopted, even for ideal cases. As an alternative, a new empirical relationship it was proposed, based on the use of different functions for operational pressure head zones.
