X-673-64-1F REV 001 DEC. â94 GODDARD SPACE FLIGHT CENTER, Greenbelt, Maryland 58 ENGINEERING DRAWING STANDARDS MANUAL The following note shall be added to the tooling drawing: THIS TOOLING IS USED TO FABRICATE PIECE PART GX-XXXXXXX.
The transfer of heat by the movement of a heated fluid is called convection. Fluids include liquids and gases. During convection, heated particles of a fluid begin to. flow, transferring heat energy from one part of the fluid to another.
Heat conduction, also called diffusion, is the direct microscopic exchange of kinetic energy of particles through the boundary between two systems. When an object is at a different temperature from another body or its surroundings, heat flows so that the body and the surroundings reach the same temperature, at which point they are in thermal equilibrium.
