  2. Eccentric reducer - Wikipedia

    en.wikipedia.org/wiki/Eccentric_reducer

    An eccentric reducer is a fitting used in piping systems between two pipes of different diameters. The same fitting can be used in reverse as an eccentric increaser or expander. The same fitting can be used in reverse as an eccentric increaser or expander.

  3. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...

  4. Concentric reducer - Wikipedia

    en.wikipedia.org/wiki/Concentric_reducer

    A concentric reducer is used to join pipe sections or tube sections on the same axis. [1] The concentric reducer is cone -shaped, and is used when there is a shift in diameter between pipes. [ 1 ] For example, when a 1" pipe transitions into a 3/4" pipe and the top or bottom of the pipe doesn't need to remain level. [ 2 ]

  5. Pressure drop - Wikipedia

    en.wikipedia.org/wiki/Pressure_drop

    Piping fittings (such as elbow and tee joints) generally lead to greater pressure drop than straight pipe. As such, a number of correlations have been developed to calculate equivalent length of fittings. [9] Certain valves are provided with an associated flow coefficient, commonly known as C v or K v.

  6. Coupling (piping) - Wikipedia

    en.wikipedia.org/wiki/Coupling_(piping)

    Alternatively it is a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female British standard pipe threads. If the two ends of a coupling are of different standards or joining methods, the coupling is called an adapter. Examples ...

  7. Hazen–Williams equation - Wikipedia

    en.wikipedia.org/wiki/Hazen–Williams_equation

    P d = pressure drop over the length of pipe in psig (pounds per square inch gauge pressure) L = length of pipe in feet; Q = flow, gpm (gallons per minute) C = pipe roughness coefficient; d = inside pipe diameter, in (inches) Note: Caution with U S Customary Units is advised. The equation for head loss in pipes, also referred to as slope, S ...

  8. Friction loss - Wikipedia

    en.wikipedia.org/wiki/Friction_loss

    Fittings, such as bends, couplings, valves, or transitions in hose or pipe diameter, or; Objects intruded into the fluid flow. For the purposes of calculating the total friction loss of a system, the sources of form friction are sometimes reduced to an equivalent length of pipe.
