Procedure for Testing and Evaluating the Performance of Friction (Drag) Reducers in Aqueous-based Fluid Flowing in Straight@ Smooth Circular Conduits (FIRST EDITION)
This document provides a consistent methodology to test and evaluate the performance of friction (drag) reducers in straight@ smooth circular conduits. This standard includes only smooth-walled tubing and excludes any rough-walled tubing. The International System of Units (SI) is used in this Technical Report. However@ testing data acquisition can be conducted using US customary units (USC). Factors included in Annex A Table A.1 permit conversions of USC units to SI units or SI units to USC units.
