2. Fire hose - Wikipedia

   en.wikipedia.org/wiki/Fire_hose

   Fire hose. Indoor fire hose with a fire extinguisher. A fire hose (or firehose) is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine, fire hydrant, or a portable fire pump. [1] Indoors, it can permanently attach to a building's standpipe or ...

   The high pressure male coupling, included in high pressure bottle connections, is set to meet the Compressed Gas Association Standards #346 and #347. Also included in the assembly are the dual-sided pressure gauge (which reads the cylinder pressure directly from the cylinder), elastomeric bumper (a protective, rubber like stop), and hangar ...

   Typical operating pressure is approximately 100–120 psi or 690–830 kPa or 6.9–8.3 bar. A compressed-air-brake system is divided into a supply system and a control system . The supply system compresses, stores and supplies high-pressure air to the control system as well as to additional air operated auxiliary truck systems (gearbox shift ...

6. Pound per square inch - Wikipedia

   en.wikipedia.org/wiki/Pound_per_square_inch

   The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), [1] is a unit of measurement of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately ...

   The vacuum draws liquid foam concentrate from a reservoir, which mixes with the water stream through a metering device on the discharge side of the eductor where a firefighting hose is connected. Typically the 200 psi inlet water pressure is reduced to 95 psi discharge pressure as a result of the narrowness of the venturi in the eductor device.
