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.

   The price had risen to $3,000 before eBay closed the auction. [8] [9] In May 2006, the remains of U.S. Fort Montgomery, a stone fortification in upstate New York built in 1844, were put up for auction on eBay. The first auction ended on June 5, 2006, with a winning bid of US$5,000,310.

4. Airbreathing jet engine - Wikipedia

   en.wikipedia.org/wiki/Airbreathing_jet_engine

   Exhaust or Nozzle – Turbine exhaust gases pass through the propelling nozzle to produce a high velocity jet. The nozzle is usually convergent with a fixed flow area. Supersonic nozzle – For high nozzle pressure ratios (Nozzle Entry Pressure/Ambient Pressure) a convergent-divergent (de Laval) nozzle is used. The expansion to atmospheric ...

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

   Uses a high-velocity stream of ultra high-pressure water 30,000–90,000 psi (210–620 MPa) which is produced by a high-pressure pump with possible abrasive particles suspended in the stream. Is used for machining a large array of materials, including heat-sensitive, delicate, or very hard materials.
