An imposible math equation?
The Colebrook-White equation was published 1937 and just about all designers of pipe say the equation is impossible to solve. But Chris taught me a trick that most pipe companies are saying “That can’t be right”.
They are wrong. I call our solution a “Trick of mind” because it is an “out of the box” method. This version of the equation is arranged to work OK in Excel. Just copy and paste.
Lets assume that RR= 0.04 and Re=200000, find F, ( F is the Darcy Friction Factor )
I think a few members of site (besides Chris) will be able to find a solution. I did in about 30 minutes. Then after working with Chris he showed me a much simpler, and quicker method that many engineers are now amazed by… some say that can’t be right, but they test it, and say WOW, it is a solution.
