WebJul 15, 2010 · The Blasius empirical correlation for turbulent pipe friction factors is derived from first principles and extended to non-Newtonian power law fluids. Two alternative formulations are obtained that both correlate well with the experimental measurements of Dodge, Bogue and Yoo. Key words: Blasius, turbulent friction factor, power law fluids WebPerte de charge. En mécanique des fluides, la perte de charge correspond à la dissipation, par frottements, de l’énergie mécanique d’un fluide en mouvement 1. Le plus souvent, le terme de perte de charge est utilisé pour quantifier la perte de pression au sein d'une canalisation générée par les frottements du fluide sur celle-ci.
