2. Darcy friction factor formulae - Wikipedia

   en.wikipedia.org/wiki/Darcy_friction_factor_formulae

   In this article, the following conventions and definitions are to be understood: The Reynolds number Re is taken to be Re = V D / ν, where V is the mean velocity of fluid flow, D is the pipe diameter, and where ν is the kinematic viscosity μ / ρ, with μ the fluid's Dynamic viscosity, and ρ the fluid's density.

3. Hazen–Williams equation - Wikipedia

   en.wikipedia.org/wiki/Hazen–Williams_equation

   The conversion factor k was chosen so that the values for C were the same as in the Chézy formula for the typical hydraulic slope of S=0.001. [9] The value of k is 0.001 −0.04. [10] Typical C factors used in design, which take into account some increase in roughness as pipe ages are as follows: [11]

4. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   Push-to-pull fittings are easily removed compression fitting that allows pipes to be connected with minimal tools. These fittings are similar to regular compression fittings but use an O-ring for sealing and a grip ring to hold the pipe. The main advantage is that it can easily be removed and re-used, it is easy to assemble, and the joints are ...

5. Plastic pipework - Wikipedia

   en.wikipedia.org/wiki/Plastic_pipework

   Pipes, fittings, valves, and accessories make up a plastic pressure pipe system. The range of pipe diameters for each pipe system does vary. However, the size ranges from 12 to 400 mm (0.472 to 15.748 in) and 3 ⁄ 8 to 16 in (9.53 to 406.40 mm). Pipes are extruded and are generally available in: 3 m (9.84 ft), 4 m (13.12 ft), 5 m (16.40 ft ...

7. Darcy–Weisbach equation - Wikipedia

   en.wikipedia.org/wiki/Darcy–Weisbach_equation

   If the value of the friction factor is 0.064, then the Darcy friction factor is plotted in the Moody diagram. Note that the nonzero digits in 0.064 are the numerator in the formula for the laminar Darcy friction factor: f D = ⁠ 64 / Re ⁠. If the value of the friction factor is 0.016, then the Fanning friction factor is plotted in the Moody ...
