Original Abstract

Paper describes various procedures for calculation of pressure drops of elbows. Elbows are categorized according to the ratio of their radius (R) and inner diameter (D), thus we may talk about long radius elbow, i.e. R/D >= 1.5, and short radius elbow, i.e. R/D < 1.5 (several sources give ratio R/D = 2 as a decisive value). It is valid that short radius gives higher pressure drops that long radius.

Keywords
