Hello,

I am working on making an Excel work book to aid in figuring out pressure drops in a system. I am trying to use the Darcy Weisbach equation for pressure loss.
http://www.engineeringtoolbox.com/da...ion-d_646.html

In Excel I have
=(C4*(C5/C6))*((C7+(SQRT(C8)))/2)

C4= Friction coefficient
C5= Length of pipe
C6= Hydraulic dia
C7= Density
C8= Velocity

Please help me out.

Should be

=(C4*(C5/C6))*((C7*(C8*C8))/2)

I hate it when that happens :)
