Newton number (also called the drag coefficient) and Archimedes number are plotted versus the Reynolds number for the laminar, transition and turbulent flow types using a log-log scale. Expressions and numerical examples of the terminal fall velocity of a single spherical particle in a Newtonian Fluid, for the three flow types, are given in the notebook. For laminar flow, the terminal velocity expression is given by the well-known Stokes’ law. Measurement of terminal fall velocity has important applications such as viscosity determination (e.g. falling-sphere viscometer) and decanter sizing.
