Water Jet

A water jet is a piece of equipment used in modern industry to cut materials. A water jet has a few advantages over a traditional milling machine including: increased accuracy and precision if the cut, never overheats and the tool never gets dull. A water jet works off a couple of fluid mechanic principles including the Bernoulli principle and the relationship of linear momentum to the resultant forces. When the water in the jet approaches the nozzle it is at a pressure between 20,000-55,000 pisg. When the water leaves the nozzle the pressure is converted to kinetic energy causing the water to travel at a velocity of 900 mph. At this velocity the resultant force is large enough to cut through steel.
