Computes the equivalent diameters ("Sauter mean diameter") before and after a treatment. The data are the quantities (weights) retained in a series of sieves. The sieves' openings are supposed to decrease by 1⁄√2.

(It is expected to include here an alternative equivalent diameter.)

The graph shows the fractions retained before and after.
