  2. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes

  3. Water jet cutter - Wikipedia

    en.wikipedia.org/wiki/Water_jet_cutter

    Water jets are capable of cutting up to 6 in (150 mm) of metals and 18 in (460 mm) of most materials, [48] though in specialized coal mining applications, [49] water jets are capable of cutting up to 100 ft (30 m) using a 1 in (25 mm) nozzle. [50] Specially designed water jet cutters are commonly used to remove excess bitumen from road surfaces ...

  4. de Laval nozzle - Wikipedia

    en.wikipedia.org/wiki/De_Laval_nozzle

    A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, with a rapid convergence and gradual divergence. It is used to accelerate a compressible fluid to supersonic speeds in the axial (thrust) direction, by converting the thermal energy of the flow into kinetic energy .

  5. Spray nozzle - Wikipedia

    en.wikipedia.org/wiki/Spray_nozzle

    Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...

  7. Nozzle - Wikipedia

    en.wikipedia.org/wiki/Nozzle

    A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid ( liquid or gas ).
