   en.wikipedia.org/wiki/Spray_(liquid_drop)

   Calcium hydroxide (lime) is atomized into a spray dryer absorber to remove acid gases (SO2 and HCl) from coal-fired power plants. Water is sprayed to remove particulate solids using a spray tower or a cyclonic spray scrubber [14] Cooling towers use spray nozzles to distribute water.

   Spray-tower scrubber wet scrubbers may be categorized by pressure drop as follows: Low-energy scrubbers (0.5 to 2.5 inches water gauge - 124.4 to 621.9 Pa) Low- to medium-energy scrubbers (2.5 to 6 inches water gauge - 0.622 to 1.493 kPa) Medium- to high-energy scrubbers (6 to 15 inches water gauge - 1.493 to 3.731 kPa)

6. Spray pond - Wikipedia

   en.wikipedia.org/wiki/Spray_pond

   Specific spray pond surface areas tend to range between 1.2 and 1.7 m 2 per m 3 /h of water to be cooled. The width chosen for a drift channel around the active zone of the pond (containing the sprays) is dependent on a number of factors, including the prevailing wind strength, the average size of the spray droplets produced by the nozzles, and the presence of any nearby structures which may ...

7. Hand pump - Wikipedia

   In parts of Britain and Ireland, it was often called the parish pump. Though such community pumps are no longer common, people still used the expression parish pump to describe a place or forum where matters of local interest are discussed. [3] Because water from pitcher pumps is drawn directly from the soil, it is more prone to contamination.
