Because of Moody's chart has demonstrated applicability of the Colebrook equation over a
very wide range of Reynolds number and relative roughness values, this equation becomes …

The Colebrook–white equation is widely used in many fields, like civil engineering for
calculation of water distribution systems and in all fields of engineering where fluid flow can …

Pressure drop in pipes can be calculated by using the Darcy-Weisbach formula. In order to
use this formula, the Darcy friction factor should be known. The best approximation to the …

The Colebrook equation is a popular model for estimating friction loss coefficients in water
and gas pipes. The model is implicit in the unknown flow friction factor, f. To date, the …

This paper presents evolutionary optimization of explicit approximations of the empirical
Colebrook's equation that is used for the calculation of the turbulent friction factor (λ), ie, for …

The empirical Colebrook equation from 1939 is still accepted as an informal standard way to
calculate the friction factor of turbulent flows (4000< Re< 108) through pipes with roughness …

The use of a passive method to enhance heat transfer performance based on the application
of shallow square dimples on the walls of flat tubes in compact heat exchangers for …

Nowadays, the Colebrook equation is used as a mostly accepted relation for the calculation
of fluid flow friction factor. However, the Colebrook equation is implicit with respect to the …

New explicit approximations to the implicitly given Colebrook equation for flow friction factor
are given. They are with improved accuracy compared with the one recently published …

Determination of friction factor (f) in pipe flow is necessary for various applications dealing
with fluid flow. The Colebrook–White equation is the most accepted technique for the f …
