Fluid mechanics, help in finding the dancy friction factor

[wmsaqqa]

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.

can you show me an example for this if there is available, please!
