A water gun using this system is pressurized by air being pumped and compressed into its reservoir. When the trigger is pulled, a valve is opened and the compressed air pushes the water out of the nozzle. [13] Super Soaker started with two pressurized reservoir water guns, and has continued to produce them in various shapes and sizes.
State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
A water timer is an electromechanical device that, when placed on a water line, increases or decreases the water flow through the use of an electro-mechanically actuated ball valve or embedded (solenoid) valve.
The National Oceanic and Atmospheric Administration (NOAA) is predicting a warmer, drier winter in the southern half of the U.S., with wetter than usual weather in northern parts of the country ...
APW extinguishers are commonly converted into makeshift CAFS extinguishers by drilling two 1.6–3.2 mm (1 ⁄ 16 – 1 ⁄ 8 in) holes in the pickup tube. The unit is then filled with 5.7 litres (1.5 US gal) of water and Class A foam, aqueous film forming foam (AFFF), film-forming fluoroprotein (FFFP) or commercial detergent is added to the water in a 1% ratio for class A fires and a 3–6% ...
A water level device showing both ends at the same height. A water level (Greek: Aλφαδολάστιχο or (υδροστάθμη) [Alfadolasticho]) is a siphon utilizing two or more parts of the liquid water surface to establish a local horizontal line or plane of reference.

Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power ...
