Sorry, yes, 10 cm, aka 1 decimeter.
Have you looked at the "Figure 4" Chart on page 6 of the
Quanshi Ye and Paul A. Wiegert .pdf ?
According to what you're suggesting,
that chart runs from 1 decimeter radius or 2 decimeters in diameter, down to 1/100 millimeter in radius or 2/100 millimeters in diameter.
1 decimeter equals 3.93700787 inches, so that chart says:
the particles are from 7.87401574 inches, down to 29 micrometers or microns which is 7.874015748031496 of 10,000ths an inch.
MEAN size (average size) of particles are a radius of -3.29871 millimeters or 1.2987047244 inches, which is a diameter of 2.5974094488 inches.
Mode size particles(there's just as many smaller particles as there are larger particles from this size)
are a radius of 29.3205 millimeters, which is 1.1543503937 inches or a diameter of 2.3087007874 inches.
And IF just ONE particle is larger than 4 inches,THEN their entire model is invalidated.
