  2. Water hammer - Wikipedia

    en.wikipedia.org/wiki/Water_hammer

    Water flowing through a pipe has momentum. If the moving water is suddenly stopped, such as by closing a valve downstream of the flowing water, the pressure can rise suddenly with a resulting shock wave. In domestic plumbing this shock wave is experienced as a loud banging resembling a hammering noise. Water hammer can cause pipelines to break ...

  3. Limescale - Wikipedia

    en.wikipedia.org/wiki/Limescale

    Limescale build-up inside a pipe reduces both liquid flow through the pipe and thermal conduction from the liquid to the outer pipe shell. Both effects will reduce the pipe's overall thermal efficiency when used as a heat exchanger. Limescale is a hard, chalky deposit, consisting mainly of calcium carbonate (CaCO 3).

  4. Teapot effect - Wikipedia

    en.wikipedia.org/wiki/Teapot_effect

    They run in the same direction as the flow itself. If the outflowing liquid hits an edge, the flow is compressed into a smaller cross-section. It only does not break off if the flow rate of liquid particles remains constant, regardless of where an imaginary cross section (perpendicular to the flow) is located.

  5. Pipe flow - Wikipedia

    en.wikipedia.org/wiki/Pipe_flow

    In fluid mechanics, pipe flow is a type of fluid flow within a closed conduit, such as a pipe, duct or tube. It is also called as Internal flow. [1] The other type of flow within a conduit is open channel flow. These two types of flow are similar in many ways, but differ in one important aspect.

    The EPA required local governments to notify people of known or potential service lines containing lead, galvanized lines requiring replacement or unknown lines.

  7. Fire hydrant - Wikipedia

    en.wikipedia.org/wiki/Fire_hydrant

    If a fire hydrant is opened or closed too quickly, a water hammer can occur and damage nearby pipes and equipment. The water inside a charged hose line causes it to be very heavy, and high-water pressure causes it to be stiff and unable to make a tight turn while pressurized. When a fire hydrant is unobstructed, this is not a problem, as there ...

  8. Circulator pump - Wikipedia

    en.wikipedia.org/wiki/Circulator_pump

    In typical one-way plumbing without a circulation pump, water is simply piped from the water heater through the pipes to the tap. Once the tap is shut off, the water remaining in the pipes cools producing the familiar wait for hot water the next time the tap is opened.

  9. Friction loss - Wikipedia

    en.wikipedia.org/wiki/Friction_loss

    r = radius of the pipe (for a pipe of circular section, the internal radius of the pipe). v = mean velocity of fluid flowing through the pipe. A = cross sectional area of the pipe. In long pipes, the loss in pressure (assuming the pipe is level) is proportional to the length of pipe involved.
