An impeller is a rotor used to increase the pressure and flow of a fluid. It is a critical component in various types of machinery, such as pumps, compressors, and engines. The design of an impeller typically consists of a series of blades that are fixed to a central hub. When the impeller rotates, it imparts kinetic energy to the fluid, causing it to flow outward from the center.
