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

Figure 5

Decreased maximal number of required iterations from 4 to 3 to reach accuracy of 10⁻⁸ for solving Colebrook’s equation in Halley’s and Schröder’s procedure when calculation goes through the transmission factor x where the initial starting point is with the fixed value: x₀ = 7.990256504.
