LINEAR PRESSURE LOSSES COEFFICIENTS IN A NEW VENTILATION SYSTEM
: This paper presents the results of research on linear losses in a new ventilation system based on channels with a rounded rectangle cross-section. The friction coefficients of linear pressure losses referred to the unit of the straight length of the duct section 1 m l − as well as generalized dimensionless friction coefficient of linear pressure losses − are presented. The main achievement of the paper is the statement that the lambda coefficient can replace the coefficients l for all 79 examined duct cross-sections.
