![]() ![]() Here, the flow time t of the polymer solution and of pure solvent t 0 are recorded. Depending on the capillary constant and temperature, relative uncertainties of. The simplest method for determining the viscosity of a polymer solution is by capillary viscometry, using the Ubbelohde U-tube viscometer.
