- The discharge of large quantities of fluid material from the body, especially the discharge of watery feces from the intestines.
- Material thus discharged from the bowels.
- The rate of flow of fluid, particles, or energy through a given surface.
- Flux density.
- The rate of flow of fluids, particles, or energy across a given surface or area.
- The presence of a field of force in a region of space, represented as a set of lines indicating the direction of the force. The density of the lines indicates the strength of the force. Lines used to represent magnetic fields in depictions of magnets, for example, follow the lines of flux of the field. See also field magnetic flux.
- A measure of the strength of such a field.
- A readily fusible glass or enamel used as a base in ceramic work.
- An additive that improves the flow of plastics during fabrication.
- A substance applied to a surface to be joined by welding, soldering, or brazing to facilitate the flowing of solder and prevent formation of oxides.
- A substance used in a smelting furnace to make metals melt more easily.
