Abstract
The measured viscosity of a suspension appears to depend upon the diameter of the tube of the capillary viscometer used in determining it. It is shown that existing theory can be brought into satisfactory agreement with experimental results if it is assumed that the interaction between the suspended particles makes the concentration uniform across the tube. The effect of the curvature of the velocity profile on particle velocity is also included.
