Word Origin and History for streamlining
streamline
1868 (n.) "line drawn from point to point, so that its direction is everywhere that of the motion of the fluid" [Lamb, "Hydrodynamics," 1906], from stream + line. The adj. is attested from 1898, "free from turbulence," 1907 in sense of "shaped so that the flow around it is smooth." The verb is attested from 1913 with meaning "give a streamline form to," and 1936 in the extended sense of "simplify and organize."

streamlining in Culture

streamline definition


The line traced by a liquid or gas as it moves. Streamlines are most commonly used in describing the flow of a liquid or gas around a solid object.

Note: A “streamlined” design is one in which objects that move through a gas or liquid are shaped to match these lines, and therefore reduce the energy required to produce that motion.
