Abstract

The paper deals with the introduction of an alternative method for the evaluation of the fluid flow rate through a square pipe, by directly measuring the flow mean velocity at a fixed location in the section area. The authors of this paper have previously introduced a way for the evaluation of the fluid flow rate, by measuring a single point flow velocity in square pipes. In this study, the authors perform a series of considerations aimed at the validation of the proposed methodology, by comparing it with prescribed procedures described by ISO 3966:2008 standard. In this standard a method for the evaluation of fluid flow rate (under specific fluid dynamic conditions) is stated from velocity measurements performed in a-priori fixed points (in a given test section and to be defined according to the cross-section shape), using a static Pitot-tube (or equivalent equipment). In this work, the authors validate the proposed simplified method against the Log-Thebycheff procedure (according to the same standard). A Laser Doppler Anemometer (LDA) has been used.
