Fanning's equation for turbulent
Webequation was found inadequate over a wide range of flow conditions. Moreover, several researchers have found that the Colebrook–White equation is inadequate for pipes smaller than 2.5 mm. Wesseling and Homma (1967) suggested using a Blasius-type equation or a power law with minor modifications instead of the Colebrook–White equation. WebAug 11, 2024 · The more exact way to calculate the Darcy friction factor for turbulent flow is using the phenomenological Colebrook-White equation: \frac {1} {\sqrt {f}} = -2 \log …
