A small metallic ball moves through a fluid with a speed v in downward direction experiences a force F which acts in upwards direction Experimentally the magnitude of this force depends on radius r of ball velocity v of ball and viscosity h of fluid The correct relation between F r v and h is given by XFx nn 2 F n rv 3 F nr v t
