Impeller vs. Turbine

Impellernoun

Something which or someone who impels, usually a part of a pump.

Impellernoun

One who, or that which, impels.

Impellernoun

the blade of a rotor (as in the compressor of a jet engine)

Impellernoun

the rotating part of a centrifugal pump, compressor, or other machine designed to move a fluid by rotation.

Impellernoun

a device turned by the flow of water past a ship's hull, used to measure speed or distance travelled.

Impeller

An impeller or impellor is a rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid.

Turbinenoun

Any of various rotary machines that use the kinetic energy of a continuous stream of fluid (a liquid or a gas) to turn a shaft.

Turbinenoun

A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; - also called turbine wheel.

Turbinenoun

A type of rotary engine with a set of rotating vanes, diagonally inclined and often curved, attached to a central spindle, and obtaining its motive force from the passage of a fluid, as water, steam, combusted gases, or air, over the vanes. Water turbines are frequently used for generating power at hydroelectric power stations, and steam turbines are used for generating power from coal- or oil-fired electric power stations. Turbines are also found in jet engines, and in some automobile engines.

Turbinenoun

rotary engine in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a bladed rotor to rotate

Turbinenoun

a machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid.

Turbine

A turbine ( or ) (from the Greek τύρβη, tyrbē, or Latin turbo, meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.
