His work is the basis of the falling sphere viscometer, in which the fluid is stationary in a vertical glass tube.
2.
A modification of the straight falling sphere viscometer is a rolling ball viscometer which times a ball rolling down a slope whilst immersed in the test fluid.
3.
The principle is also applied in the falling sphere viscometer, an experimental device used to measure the viscosity of highly viscous fluids, for example oil, parrafin, tar etc.
