  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 ...

    The equation was found to match the Colebrook–White equation within 0.0023% for a test set with a 70-point matrix consisting of ten relative roughness values (in the range 0.00004 to 0.05) by seven Reynolds numbers (2500 to 10 8).

    The Darcy-Weisbach equation can be used equivalently with either the fanning friction factor or the Darcy Weisbach friction factor, however if the fanning factor is used the diameter D in the equation must be replaced with the hydraulic radius.74.60.57.253 04:16, 4 November 2009 (UTC)

  6. Pipe network analysis - Wikipedia

    en.wikipedia.org/wiki/Pipe_network_analysis

    Given a starting node, we work our way around the loop in a clockwise fashion, as illustrated by Loop 1. We add up the head losses according to the Darcy–Weisbach equation for each pipe if Q is in the same direction as our loop like Q1, and subtract the head loss if the flow is in the reverse direction, like Q4.

  7. 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.

  8. Day-year principle - Wikipedia

    en.wikipedia.org/wiki/Day-year_principle

    The day-year principle was partially employed by Jews [7] as seen in Daniel 9:24–27, Ezekiel 4:4-7 [8] and in the early church. [9] It was first used in Christian exposition in 380 AD by Ticonius, who interpreted the three and a half days of Revelation 11:9 as three and a half years, writing 'three days and a half; that is, three years and six months' ('dies tres et dimidium; id est annos ...
