Although it is a trivial fact that the coefficient of loss of head due to branching and confluence are affected by the radius of curvature or shape of branch corner, quantitatively trustworthy data are lacking. The author has carried out a series of flow tests in rectangular T type ducts with variable branch corner, and presented the coefficients in relation to the radius of curvature. Dimensions of the duct are 100×100mm in main line and 100×100, 75×100, 50×100, 25×100mm in branch line. The Reynolds' number of the main flow ranges from 2×10⁵ to 3×10⁵. Many stream-line photos of branching and confluence are referred for the illustrations.
