Advanced Iterative Procedures for Solving the Implicit Colebrook Equation for Fluid Flow Friction

Figure 3

Decreased maximal number of required iterations from 6 to 4 to reach accuracy of 10⁻⁸ for solving Colebrook’s equation in Newton’s procedure when calculation goes through the transmission factor x where the initial starting point is with the fixed value: x₀ = 6.44569593948452.
