Title: Forces on a sphere moving steadily along a circular path in a viscous fluid
Description: Forces on a sphere moving steadily along a circular path in viscous fluid are measured and it is found that within the experimental range both the longitudinal and normal forces are dependent on the Reynolds number and not on the radius of the path. Thus, the conventional drag coefficient can also be obtained from a rotational motion. (Author).
