Nomogram for the settling velocity of spheres

Of primary importance to many professions is a knowledge of the rate at which a body will fall through a fluid medium. This problem plays an obvious role in the laboratory analysis of sediment, but it is also encountered in such varied fields as meteorology, mining engineering, sanitary engineering, and river hydraulics. The basic problem differs little in these several fields; indeed, many of the latest advances in the subject have resulted from research in still another science -- fluid mechanics.
