Example

A rectangular parallelepiped has sides 200 m x 100 m x 20 m. Determine:

(1) The characteristic dimension, by: (i) projected area diameter, da

(ii) equivalent surface diameter, ds, based on the sphere (iii) equivalent volume diameter, dy, based on the sphere (iv) sieving, Ls.

(2) From the 'sieve size' determine:

(a) the surface shape factor

(b) the volume shape factor

(c) the specific surface shape factor

(d) the sphericity, from first principles.
