  2. Darcy–Weisbach equation - Wikipedia

    en.wikipedia.org/wiki/DarcyWeisbach_equation

    μ is the dynamic viscosity of the fluid (Pa·s = N·s/m 2 = kg/(m·s)); Q is the volumetric flow rate, used here to measure flow instead of mean velocity according to Q = ⁠ π / 4 ⁠ D c 2 <v> (m 3 /s). Note that this laminar form of Darcy–Weisbach is equivalent to the Hagen–Poiseuille equation, which is analytically derived from the ...

  3. Darcy friction factor formulae - Wikipedia

    en.wikipedia.org/wiki/Darcy_friction_factor_formulae

    In fluid dynamics, the Darcy friction factor formulae are equations that allow the calculation of the Darcy friction factor, a dimensionless quantity used in the Darcy–Weisbach equation, for the description of friction losses in pipe flow as well as open-channel flow.

  4. Darcy's law - Wikipedia

    en.wikipedia.org/wiki/Darcy's_law

    A is the cross sectional area (m 2) of the cylinder. Q is the flow rate (m 3 /s) of the fluid flowing through the area A. The flux of fluid through A is q = Q/A. L is the length of the cylinder. Δp = p outlet - p inlet = p b - p a. = Δp/L = hydraulic gradient applied between the points a and b.

    It contains a part that is solidly grounded in theory (the v^2/2g term, and to a lesser extent the L/D term) and the term "semi-empirical equation" is in more common use than "phenomenological equation"Mikejens 16:06, 12 November 2008 (UTC) The Darcy–Weisbach equation is exact for laminar flow and can be derived theoretically.

    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] Measurements of fluid flow in artificially roughened pipes by J. Nikuradse [5] were at the time too recent to include in Pigott's chart.
