Progress CheckDirections: After answering the following questions, compare your answers with those provided inthe answer key following this progress check. If you respond to any items incorrectly, return to thetext and review the appropriate topics.For questions 1-4, match the atomization process with its description. In addition, write a G in thespace next to the atomization processes used in Graco fluid handling equipment.Atomization Processesa. Pressure (airless) _______b. Air (airspray) _______c. Centrifugal _______d. Electrostatic _______e. Ultrasonic ___________ 1.____ 2.____ 3.____ 4.____ 5.Introduction of fluid to the center of a spinning disk; the fluid breaks up into fine dropletsas it flows off the disk’s edgePassing fluid over a vibrating device that causes a breaking up of the fluid into dropletsExposing a fluid to an electric field that tears the droplets from the atomizer and propelsthem toward the work surfaceForcing a fluid through an orifice at high speed; friction between the fluid and the airdisrupts the fluid stream and breaks it up into dropletsA high pressure air stream that surrounds fluid under low pressure; friction disrupts thefluid stream and breaks it up into droplets6. Describe the difference between electrostatic atomization and electrostatic spray charging.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________14Atomization®
