The Darcy-Weisbach's accuracy and universal applicability makes it the ideal formula for flow in pipes. The advantages of the equation are as follows:
* It is based on fundamentals.
* It is dimensionally consistent.
* It is useful for any fluid, including oil, gas, brine, and sludges.
* It can be derived analytically in the laminar flow region.
* It is useful in the transition region between laminar flow and fully developed turbulent flow.
* The friction factor variation is well documented.
