A robust, fast and accurate method for solving the Colebrook-like equations is presented. The algorithm is efficient for the whole range of parameters involved in the Colebrook equation. The computations are not
more demanding than simplified approximations, but they are much more accurate. The algorithm is also faster and more robust than the Colebrook solution expressed in term of the Lambert W-function. Matlab c and FORTRAN codes are provided.

An Introduction to Colebrook Equation and its solutions using MS Excel

A straight forward method to solve Colebrook Equation in Excel or OpenOffice is presented in the book:

The following papers appeared in web describes various alternatives of Colebrook Equation and methods existing  by Thomas G. Lester, P.E., Bergmann Associates

The author sugges VBA and UDFs as the methods by which Colebrook Equation be solved!
