For example, 17 identifications in the grain 60a found insignificant fluctuations of fineness within interval 992–1000‰, and 13 identifications in the grain 60b showed the highest gold fineness – 1000‰.
Does increased fineness ratio decrease skin friction drag?
WebOnce that optimal fineness level is determined, maintaining a consistent grain structure becomes a critical factor in the quality of the final castings. Sand that is too fine (higher GFN) can create low permeability and result in gas defects. Sand that is too coarse (lower GFN) can create high permeability and lead to problems with metal ...
