One-Log Call Iterative Solution of the Colebrook Equation for Flow Friction Based on Padé Polynomials

open access: yesEnergies, 2018
The 80 year-old empirical Colebrook function ξ, widely used as an informal standard for hydraulic resistance, relates implicitly the unknown flow friction factor λ, with the known Reynolds number Re and the known relative roughness of a pipe ...
