where \( Re \) is the Reynolds number. However, as the flow transitions to a turbulent regime, the calculation becomes more complex. The turbulent flow friction factor is determined using empirical correlations, such as the Colebrook-White equation, which accounts for both the Reynolds number and the relative roughness of the pipe.
