2. High pressure jet - Wikipedia

   en.wikipedia.org/wiki/High_pressure_jet

   Contour animation of the mole fraction variation (from 0.025 to 0.05) of a Natural Gas jet as it impinges a steel tank done through CFD.. A high pressure jet is a stream of pressurized fluid that is released from an environment at a significantly higher pressure than ambient pressure from a nozzle or orifice, due to operational or accidental release.

3. Water cannon - Wikipedia

   en.wikipedia.org/wiki/Water_cannon

   Ultra high pressure water jet cutters are used to cut a wide variety of materials including granite, concrete (see hydrodemolition), ceramics, fabric and even Kevlar. [15] One such cutter delivers 55,000 psi (380 MPa) through a nozzle 0.003 inches (76 μm) in diameter at 1 kilometre per second, which can cut a person at a close range.

   Harbor Freight Tools, commonly referred to as Harbor Freight, is an American privately held tool and equipment retailer, headquartered in Calabasas, California. It operates a chain of retail stores, as well as an e-commerce business. The company employs over 28,000 people in the United States, [5] and has over 1,500 locations in 48 states. [6] [7]

5. Nozzle - Wikipedia

   en.wikipedia.org/wiki/Nozzle

   A de Laval nozzle has a convergent section followed by a divergent section and is often called a convergent-divergent (CD) nozzle ("con-di nozzle"). Convergent nozzles accelerate subsonic fluids. If the nozzle pressure ratio is high enough, then the flow will reach sonic velocity at the narrowest point (i.e. the nozzle throat ).

6. Propelling nozzle - Wikipedia

   en.wikipedia.org/wiki/Propelling_nozzle

   Convergent nozzles are used on many jet engines. If the nozzle pressure ratio is above the critical value (about 1.8:1) a convergent nozzle will choke, resulting in some of the expansion to atmospheric pressure taking place downstream of the throat (i.e., smallest flow area), in the jet wake. Although jet momentum still produces much of the ...

7. Water jet cutter - Wikipedia

   en.wikipedia.org/wiki/Water_jet_cutter

   In 1956, Carl Johnson of Durox International in Luxembourg developed a method for cutting plastic shapes using a thin stream high-pressure water jet, but those materials, like paper, were soft materials. [4] In 1958, Billie Schwacha of North American Aviation developed a system using ultra-high-pressure liquid to cut hard materials. [5]
