## Homework Statement

if we have only a measuring cylinder (500mm high and 50mm diameter), a stop-watch, a ruler and a 100μL syringe. We assume that the density of the suspension is 1g/cm3, and that the polymers are spherical How can we determine the viscosity and the volume fraction of the polymers in solution?

## Homework Equations

Strokes Law and Einstein equation

## The Attempt at a Solution

To measure viscosity of liquid I normally think of a falling sphere object known mass and density in a cylinder contain a unknown viscosity sample. So I can use Strokes' Law to find the viscosity and Einstein equation to find a volume fraction.

But No sphere object is provided in this question.

Any idea what to do with syringe.

Thanks
