The Colebrook-White equation is used to iteratively calculate for the Darcy-Weisbach friction factor:
| |
f |
= |
Friction factor (unitless) |
| |
k |
= |
Darcy-Weisbach roughness height (m, ft.) |
| |
Re |
= |
Reynolds Number (unitless) |
| |
R |
= |
Hydraulic radius (m, ft.) |
| |
D |
= |
Pipe diameter (m, ft.) |
