Homework Help: Measurement of viscosity of polymer

  1. May 24, 2015 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations
    Strokes Law and Einstein equation

    3. 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.
