darcy_weisbach: Darcy Weisbach equation

In ratral/hyd4gpv: General Purpose Valve functions

Description

In fluid dynamics, the Darcy–Weisbach equation is an empirical equation, which relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The Darcy–Weisbach equation contains a dimensionless friction factor, known as the Darcy friction factor. This is also variously called the Darcy–Weisbach friction factor, friction factor, resistance coefficient, or flow coefficient. See more about the Darcy–Weisbach equation at the Darcy–Weisbach equation
