Pipe Friction: Darcy–Weisbach, f = 64/Re for Laminar Flow and the Explicit Swamee–Jain Formula
This lesson is part of the course
In this lesson
You look up roughness values, calculate the relative roughness of six turbulent lines, their friction factor with the explicit Swamee–Jain formula and the Darcy–Weisbach head loss, and the laminar friction factor of an oil line.
