Previous: Pleau and Pigeon The equation for G given in Eqn. 13
for the sphere distribution of Eqn. 11 can also be used to
approximate the correct value of G for the zeroth-order
logarithmic distribution used here. The parameters a and b in
Eqn. 11 are chosen to yield a sphere diameter distribution with
the same modal diameter Dm and specific surface as the
logarithmic distribution used here. The specific surface and the
modal diameter are related to the parameters from the following
equations: The corresponding values of the parameters are The
corresponding equation for G is Note again that the value of the
numerator differs very little from that in Eqn. 10. Since the
distribution proposed by Attiogbe is based upon the zeroth-order
logarithmic function used here, it is reasonable to expect that
a corrected form for Eqn. 13 which is based the zeroth-order
logarithmic distribution would differ very little from the above
result. It is this equation for G
