Efficiency vs. Streamline

Efficiency and Streamline Definitions
Efficiency
The quality or property of being efficient.
Streamline
To construct or design in a form that offers the least resistance to fluid flow
Streamline a car's design.
Efficiency
The degree to which this quality is exercised

Efficiency
The ratio of the effective or useful output to the total input in any system.
Streamline
To improve the efficiency of, often by simplification
Streamline a factory process.

Streamline
(physics) A line that is tangent to the velocity of flow of a fluid; equivalent to the path of a specific particle in that flow.
Efficiency

Streamline
Of or pert. to a stream line; designating a motion or flow that is free from turbulence, like that of a particle in a streamline; hence, designating a surface, body, etc., that is designed so as to afford an unbroken flow of a fluid about it, esp. when the resistance to flow is the least possible; as, a streamline body for an automobile or airship; - the current usuage prefers the term streamlined.
Streamline
To design or modify so as to present the least possible resistance to fluid flow; - used mostly of vehicles, such as automobiles, airplanes, or ships.
Streamline
To change so as to make more efficient; - used especially of organizations, procedures, or methods.
Streamline
Contour economically or efficiently
