The Darcy friction factor for laminar flows is a consequence of-

Explanation:

Friction Factors

• The Laminar flow friction factor using Reynolds new dimensionless number, a friction factor for use in Weisbach's friction head equation may be found for the laminar flow regime.
• Grouping the variables of the Reynolds number in the Hagen-Poiseuille law and grouping the remaining variables as in Weisbach's equation yields the following formula for Laminar friction factor.
• \(f=\frac{64}{Re}\)
• The Laminar friction factor is a function of Reynolds number alone, and is independent of any other factor.
