Since the mass of a particle is proportional to its class, the total mass of a particle population can be calculated as :
(19–4) |
Note that is the mass of a bulk species molecule comprising the particle core and is
constant. The total mass of a particle population can be expressed in a simple form as
Equation 19–5
.
(19–5) |
Here,
(19–6) |
is the first moment of the discrete particle-size distribution function
. The average particle mass of the population can be obtained by dividing
the total particle mass by the number of particles and is given in Equation 19–7
,
(19–7) |
where is the average particle class of the population.
