Terminal Fall Velocity of a Single Spherical Particle in a Newtonian Fluid

Computes terminal fall velocity

Description

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. A numerical example of the terminal fall velocity computation of a single spherical particle in a Newtonian fluid, for the turbulent flow type, is given in the program. 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.
