Pipe Curvature Loss Coefficient The coefficient for pressure losses due to geometry changes comprises an angle correction factor, Cangle, and a bend coefficient, Cbend: The block calculates Cangle as: where θ is the value of the Bend angle parameter, in degrees. The block calculates Cbend...
The head loss across the pipe bend increases as the solid concentration of slurry increases and decreases as the proportion of an additive increases. Losses occurring in bend curves were given in terms of bend loss coefficient. The bend loss coefficient decreased as flow velocity increased and ...
Minor loss coefficients for components used in pipe and tube systems. Minor or dynamic pressure loss in pipe or tube system components can be expressed as Δ pminor_loss = ξρf v2/ 2 (1) where ξ = minor loss coefficient Δ pminor_loss = minor pressure loss (Pa (N/m2), psf...
In the application of the Toms' effect to hydraulic transportation of solids in pipelines, it is a very important problem to evaluate the pressure loss in pipe bends. In this paper we describe an experimental study of the pressure loss in a vertical pipe bend flow. The fluids used in this...

Because it is only supplied in straight lengths, changes in direction are sharp, which means that the pressure loss at a right angle bend is greater than for a steel swept bend. TABLE 7. Aluminium pipe – properties Bore (mm)External dimension (mm)Weight kg/m 12 14 0.16 25 28 × 49 ...
In this article, an interactive teaching methodology has been implemented to investigate the hydrodynamics in various pipe fittings (elbow, bend, Tee, and reducer) by actually visualizing the flow. The three-dimensional flow visualization is used to demonstrate the non-idealities such as separation,...
