The Rosin-Rammler equation

The Rosin-Rammler equation used to determine the size distribution is as follows:

mp = 100 * (1 - exp * (-(d/a)**b))

where: mp = mass fraction passing (%) d = particle diameter a = size at which (100/e) = 36.8% of particles retained b = constant = slope of the plot of ln(100/wp) vs ln x
