The Colebrook-White Equation

The Colebrook-White equation is a pivotal mathematical formula in fluid dynamics facilitating the calculation of the Darcy friction factor. Developed by Cyril Frank Colebrook and Charles Metcalf White in 1937, this equation revolutionized the field of hydraulic engineering.

While numerical solutions and approximations have been developed to simplify calculation, the Colebrook-White equation cannot be solved explicitly.
