Dictionary definition of impeller

A rotating component within a machine or device that is responsible for creating fluid flow or generating propulsion.
"The turbine's impeller blades captured the force of the flowing river, generating electricity."

Detailed meaning of impeller

An impeller is typically found in pumps, turbines, or other mechanical systems where the movement of a fluid is crucial. It consists of curved blades or vanes attached to a central hub, designed to accelerate and direct the fluid in a specific direction. As the impeller rotates, it imparts energy to the fluid, causing it to move or circulate within the system. The shape, size, and arrangement of the impeller blades play a crucial role in determining the efficiency and performance of the device. In applications such as pumps, the impeller draws in fluid and then forces it outward, creating pressure and increasing the flow rate. Impellers are essential components in various industries, including water treatment, aerospace, automotive, and marine, where the controlled movement of fluids is vital for the operation of machinery and equipment.

History and etymology of impeller

The noun 'impeller' finds its origins in the verb 'impel,' which comes from the Latin word 'impellere.' 'Impellere' is a combination of 'in' (meaning 'toward') and 'pellere' (meaning 'to drive' or 'to push'). In Latin, 'impellere' described the act of driving or pushing something forward. When this term transitioned into English and evolved into 'impeller,' it specifically referred to a rotating component within a machine or device responsible for creating fluid flow or generating propulsion by pushing or driving fluid or air in a particular direction. The etymology of 'impeller' underscores its connection to the concept of driving or pushing, emphasizing its role in engineering and technology as a crucial component that imparts motion and fluid movement within various mechanical systems.
