  2. Hydronics - Wikipedia

    en.wikipedia.org/wiki/Hydronics

    The two-pipe reverse return configuration which is sometimes called 'the three-pipe system' is different from the two-pipe system in the way that water returns to the boiler. In a two-pipe system, once the water has left the first radiator, it returns to the boiler to be reheated, and so with the second and third etc.

    en.wikipedia.org/wiki/Talk:Hydronics

    Hydronics is the name for the use of liquid water (or aqueous solutions) as the heat-transfer medium in heating and cooling systems. The chapter on pipe sizing in the ASHRAE Handbook of Fundamentals has separate sections for "Hydronic System Piping" (as a subsection of "Water Piping") and "Steam Piping" (as its own major section).

  4. Pipe network analysis - Wikipedia

    en.wikipedia.org/wiki/Pipe_network_analysis

    In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.

  6. Hydronic balancing - Wikipedia

    en.wikipedia.org/wiki/Hydronic_balancing

    Hydronic balancing, also called hydraulic balancing, is the process of optimizing the distribution of water in a building's hydronic heating or cooling system by equalizing the system pressure. In a balanced system every radiator is set to receive the proper amount of fluid in order to provide the intended indoor climate at optimum energy ...

  7. Water hammer - Wikipedia

    en.wikipedia.org/wiki/Water_hammer

    Steam hammer can occur in steam systems when some of the steam condenses into water in a horizontal section of the piping. The steam forcing the liquid water along the pipe forms a "slug" which impacts a valve of pipe fitting, creating a loud hammering noise and high pressure. Vacuum caused by condensation from thermal shock can also cause a ...

  8. Flow distribution in manifolds - Wikipedia

    en.wikipedia.org/wiki/Flow_distribution_in_manifolds

    The flow in manifolds is extensively encountered in many industrial processes when it is necessary to distribute a large fluid stream into several parallel streams, or to collect them into one discharge stream, such as in fuel cells, heat exchangers, radial flow reactors, hydronics, fire protection, and irrigation. Manifolds can usually be ...

  9. Hardy Cross method - Wikipedia

    en.wikipedia.org/wiki/Hardy_Cross_method

    The Hardy Cross method is an iterative method for determining the flow in pipe network systems where the inputs and outputs are known, but the flow inside the network is unknown. [1] The method was first published in November 1936 by its namesake, Hardy Cross, a structural engineering professor at the University of Illinois at Urbana ...
