Abstract
Frictional resistance coefficients have been calculated for the rotation of spheres in non-Newtonian power-law fluids under laminar boundary-layer conditions using the approximate method of integral momentum balances. The values obtained agree satisfactorily with the available experimental data and the published theoretical solution.
