WebIn 1939, Colebrook found an implicit correlation for the friction factor in round pipes by fitting the data of experimental studies of turbulent flow in smooth and rough pipes. For hydraulically smooth pipe and the turbulent flow (Re < 10 5 ), the friction factor can be approximated by the Blasius formula: f = (100.Re)-¼. WebThe Colebrook White equation calculates the velocity (v) of flow through a circular pipe running full using the below equation; Gravitational Constant (g) (m/s 2 ) This is the …
WebApr 6, 2024 · The Colebrook equation from 1939 [1], Eq. (1), is an informal standard widely accepted in engineering practice for calculation of turbulent Darcy’s fluid flow friction factor. It is an empirical equation based on an experiment with air flow through a set of smooth to fully rough pipes performed by Colebrook and White in 1937 [2].
