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.
The process of convection is the main means of heat transfer within a fluid that is exposed to a heat source. Usually, the fluid, which can be a liquid or a gas, is heated from below by a warm surface; the increase in temperature results in a decrease in density, causing the fluid to rise and cooler fluid to flow inward to replace it.
