Reconsideration of the friction factor data and equations for smooth, rough and transition pipe flow
Faculty of Mechanical Engineering of the University of Belgrade,
Kraljice Marije 16,
The key element in design of pipelines is the friction factor estimation. After the brief review of the experimental data and friction factor correlations for isothermal single phase flow, we have checked the validity of well-known correlations through statistical criteria. During this process it was statistically proved that some of the well-known and permanently cited friction factor equations can be improved. Moreover we have prepared, for practical engineering purposes, equations that cover the entire range of laminar, critical and turbulent pipe flow.
