Se analiza el tamao de partcula de dos polvos de tungsteno diferentes (densidad terica = 19,3 g/ cm3 ) usando una tcnica de flujo y se encuentra que tienen un tamao medio equivalente de 5 micrmetros. Sin embargo, otras propiedades son bastante diferentes.

Polvo A - rea especfica (m 2 /g) = 0,26, densidad aparente (g/cm 3 ) = 2,3, densidad aparente (g/cm 3 ) = 4,6

Polvo B: rea especfica (m 2 /g) = 0,12, densidad aparente (g/cm 3 ) = 4,5, densidad aparente (g/cm 3 ) = 8,1

a) Explica por qu podra haber una diferencia en las reas de superficie.

b) Qu dimetro esfrico equivalente dara las mismas reas superficiales para cada polvo?

c) Qu diferencias podran explicar las propiedades de empaquetamiento?

d) Qu informacin adicional sera til?
