The Modified Rosin-Rammler equation

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

mp = 100 * (1 - exp * (–0.693147(d/d50)**m))

where: mp = mass fraction passing (%) d = particle diameter d50 = size at which 50% of particles retained by mass m = sharpness constant

Returns:
