Drip formation decrease

For a liquid (for example, water), the size of a drop formed at a sharp-edged tube opening can be reduced from 3.6 mm to 784 pm if the opening diameter decreases from 1 mm to 10 pm. Apparently, the dripping mechanism is concerned with large drops and low liquid flow rates. Therefore, it is a functional mechanism in drop formation processes common in nature. [Pg.125]

There is another condensed-phase mode of action that is specific for aliphatic bromine, and it is the opposite of char formation. Bromine radicals generated thermally at low temperature in the polymer melt can cause chain scission at tertiary C atoms.Examples of polymers where this mechanism is operational are polystyrene (foams) and polypropylene (preferably thin parts, films, or fibers). The decreased molecular weight causes fast dripping of the hot polymer, which cools the flame and eventually extinguishes it ... [Pg.10]
