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 ... WebThe significance of fineness modulus (FM) is in specifying the proportions of fine and coarse aggregates when designing concrete mixes. The higher the value of FM, the …

Web18 de mai. de 2024 · The higher fineness ratio gives a longer flowpath, slowing the air more (=higher Reynolds). A slower boundary layer creates less friction downstream. But increasing the fineness ratio increases the total surface area as well. And that is a recipe for increased friction. From the Wikipedia article on fineness ratio: WebThe penetration of high-fineness-ratio copper projectiles into aluminum targets is presented in figure 1. The penetration, in units of projectile length, is plotted versus the inclination angle, in degrees. The data shown represent impacts by projectiles with diameters of 0.0044, 0.0029, 0.0014, and 0.0007 inch ...
