Abstract: Explicit equations are developed for the drag coefficient and for the terminal velocity of falling spherical and non-spherical particles. The goodness of fit of these equations to the reported experimental data is evaluated and is compared with that of other recently proposed equations.Accurate design charts for C_D and u_t are prepared and displayed for all particle sphericities.
