Résumé

In compiling a revision to the CIBSE Guide on fluid flow in pipes and ducts, a survey was undertaken of available data on pressure loss factors of fittings. This paper details some of the contradictory information concerning components of ductwork. This paper makes no attempt to include all the comparisons which were made. Rather, it highlights a few of the glaring contradictions and possible errors in hitherto accepted data. In trying to assemble data which is reliable and simple to use in day-to-day design work, the author has been presented with several dilemmas. The more contentious of these, and the final decisions taken, are explained.
