High-pressure water jets are powerful streams of water that are expelled at high speeds, often used for cleaning and cutting. These jets can reach pressures of up to 40,000 psi (pounds per square inch) or more, making them effective for removing dirt, grime, and other materials from surfaces. They are commonly used in industries such as construction, automotive, and manufacturing. The technology behind high-pressure water jets involves specialized pumps and nozzles that create a focused stream. This method is also utilized in water jet cutting, where the high-pressure water can slice through materials like metal, stone, and glass with precision, making it a versatile tool in various applications.
