  2. Moody chart - Wikipedia

    en.wikipedia.org/wiki/Moody_chart

    This chart became commonly known as the Moody chart or Moody diagram. It adapts the work of Hunter Rouse [ 2 ] but uses the more practical choice of coordinates employed by R. J. S. Pigott , [ 3 ] whose work was based upon an analysis of some 10,000 experiments from various sources. [ 4 ]

  3. Darcy–Weisbach equation - Wikipedia

    en.wikipedia.org/wiki/Darcy–Weisbach_equation

    Which 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.

    en.wikipedia.org/wiki/Lewis_Ferry_Moody

    Lewis Ferry Moody (5 January 1880 – 18 April 1953 [1]) was an American engineer and professor, best known for the Moody chart, a diagram capturing relationships between several variables used in calculating fluid flow through a pipe. He has 23 patents for his inventions. [2]

  5. Fanning friction factor - Wikipedia

    en.wikipedia.org/wiki/Fanning_friction_factor

    This was originally produced to describe the Moody chart, which plots the Darcy-Weisbach Friction factor against Reynolds number. The Darcy Weisbach Formula f D {\displaystyle f_{D}} , also called Moody friction factor, is 4 times the Fanning friction factor f {\displaystyle f} and so a factor of 1 4 {\displaystyle {\frac {1}{4}}} has been ...

  6. Darcy friction factor formulae - Wikipedia

    en.wikipedia.org/wiki/Darcy_friction_factor_formulae

    Before choosing a formula it is worth knowing that in the paper on the Moody chart, Moody stated the accuracy is about ±5% for smooth pipes and ±10% for rough pipes. If more than one formula is applicable in the flow regime under consideration, the choice of formula may be influenced by one or more of the following:
