WebWhich friction factor is plotted in a Moody diagram may be determined by inspection if the publisher did not include the formula described above: Observe the value of the friction factor for laminar flow at a Reynolds number of 1000. If the value of the friction factor is 0.064, then the Darcy friction factor is plotted in the Moody diagram. WebMoody diagram: Fanning friction factor, f, vs. Reynolds number for the range of commercial pipe relative roughnesses. Since commercial pipe is normally relatively smooth, with an ε/D of between 0.002 and 0.0002, it follows approximately Blasius's equation for perfectly smooth pipe, with ε = 0, up to a Reynolds number of 100000: byakko tattoo https://northeastrentals.net
