Previous work on the slow motion of drops in non‐Newtonian liquids has been reviewed. The variational principles have been employed to obtain approximate upper and lower bounds on drag force experienced by a fluid sphere moving slowly in Carreau model fluids. The paper is concluded by presenting a comparison with the appropriate experimental data available in the literature.
