Fluid mechanics, help in finding the dancy friction factor

  1. Nov 20, 2013 #1
    How to find the dancy friction factor by using the colebrook white equation (not using the moody chart) ; to calculate the 1/√f = -2LOG[(e/d)/3.71 + 2.51/(Re*√f)]

    help please

    The Darcy friction factor is solved using an iterative process. You have to use a starting gues value for f and then plug the answer in and repeat until you get the f's on either side of the equation to balance.
