Streakline vs. Streamline — What's the Difference?

A locus of points of all the fluid particles that have passed continuously through a particular spatial point in the past.

To construct or design in a form that offers the least resistance to fluid flow

To design with flowing, graceful lines

To improve the efficiency of, often by simplification

A line that is parallel to the direction of flow of a fluid at a given instant.

The path of one particle in a flowing fluid.

A contour of a body constructed so as to offer minimum resistance to a fluid flow.

(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.

(meteorology) On a weather chart, a line that is tangent to the flow of the wind.

(transitive) To design and construct the contours of a vehicle etc. so as to offer the least resistance to its flow through a fluid.

To simplify or organize a process in order to increase its efficiency.

(transitive) To modernise.

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.

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.

To change so as to make more efficient; - used especially of organizations, procedures, or methods.

Contour economically or efficiently
