Determination of specific surface from a volume mass count

3 Determination of. specific surface from a volume (mass) count [Pg.90]

Consider a particle size distribution determination by mass where the fractional masses (volume =f) of particles of mean diameters (d ) are determined. For a sieve analysis, for example, the measured diameters are [Pg.90]

Example Determination of specific surface from sieve analysis data Table 2.7 Calculation of mass specific surface from sieve analysis data [Pg.93]

Sieve size (pm) Mean sieve size (dj Mass fraction residing on sieve i lr) Surface area factor (cm2 cm-3) [Pg.93]

From the data in Table 2.7, the volume specific surface by sieving is 509 cm cm. For a powder of density 2500 kg m-3 this becomes [Pg.93]
