Lewis Moody solved the Colebrook equation to create what is known today as a Moody Diagram or Moody Chart. Since three … See more The above calculator uses the Haaland equation, an explicit approximation of the Colebrook equation, to calculate the friction factor. See more The Colebrook equation is an implicit equation. That means there is no way to arrange the equation to get the Darcy friction factoron one side of the equal sign. Therefore, iteration is required to solve the Colebrook equation. See more Typically, the Colebrook Equation is used to estimate the Darcy-Weisbach friction factor, f. The friction factor can then be input into the Darcy … See more The Colebrook white equation was not derived from first principles, rather it was developed based on curve fitting to empirical data.
