7.3.3.1 Abrasive water jet cutting. The abrasive water jet process utilizes an ultra-high pressure intensifier pump that pressurizes water up to 55,000 psi (3,800 bar), forcing it through a small nozzle, typically 0.03 inch (0.76 mm) in diameter. This generates a high-velocity water jet stream at speeds of up to 3,000 feet per second (914 m/ sec).
