The viscosity, µ of a liquid can be measured by determining the time, t, it takes for a sphere of diameter, d, to settle slowly through a distance, l, in a vertical cylinder of diameter, D, containing the liquid. Assume that

t = f(l, d, µ, Δγ )

where ?γ is the difference in specific weights between the sphere and the liquid. Use dimensional analysis to show how t is related to µ, and describe how such an apparatus might be used to measure viscosity.
