Popis:	The results of an experimental study of hydraulic resistance of a laminar flow with air stream macrovortices in a long tube with inserted straight and twisted tapes are presented. It was found that there is a minimum in the relationship of the hydraulic resistance coefficient with the rotation pitch of the tape inserted into the tube. An empirical equation, recommended for use in a wide tape rotation pitch variation range, has been derived for calculating hydraulic resistance.
