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 moves through a material at a specific rate. The rate it travels depends on the material itself: some materials allow heat to move quickly through them, some materials allow heat to move very slowly through them. When heat is applied to a portion of a material, that heat will move through the material.This movement of heat through a material is called the thermal current. Depending on the composition of the atoms of that material, the heat may move very slowly, or it may move very quickly.hen heat is applied to a portion of a material, that heat will move through the material.
