what is a fanning friction factor?

[knight92]

in this paper:

http://www.sid.ir/en/VEWSSID/J_pdf/119320101807.pdf

on page 65 it says fanning friction factor has to be applied to find nusselts number for the radiator coolant but it doesnt state what it is. What is this factor ? is this to do with a fan that goes on the radiator ?

Thank you.

You read 4 pages into that document and your first question is Fanning Friction Factor? Putting that phrase into a Google search will point you to a Wikipedia article that discusses it pretty well. Don't like Wikipedia? There are 34,000 other links.

Yes. Why turn to others so fast when a little digging will get you what you want to know?

While its true that there are many links to this if you google- or just try wikipedia - in shorts: Its the same as 1/4 of the Darcy friction factor - no more no less
