Colebrook Formula Solver (For Newtonian Fluids)
Equivalent Roughness values for some common pipe material.
|Equivalent Roughness, ε|
|Riveted steel||0.003 - 0.03||0.9 - 9.0|
|Concrete||0.001 - 0.01||0.3 - 3.0|
|Wood stave||0.0006 - 0.003||0.18 - 0.9|
|Commercial steel or wrought iron||0.00015||0.045|
|Plastic, glass||0.0 (smooth)||0.0 (smooth)|
This solver uses a the bisection method to converge to a solution for friction factor. As can be seen, the current version forces the user to enter values in US Customary units. A future update will allow SI units.
In an effort to aide the user, three options are provided for fluid: Water, Air, or Other. If the user selects Water or Air, standard condition values are automatically entered into the density and viscosity inputs. In addition, the units of volume flow rate depend on the chosen fluid (mainly based on industry standard units). These values are free to be modified by the user.
