Capillary Viscometer

Poiseuille flow (steady laminar flow of an incompressible fluid) in a horizontal circular-section conduit enables determination of the dynamic viscosity of liquids, i. e. their resistance to flow.

For such a flow, the fluid flow rate and pressure drop in the conduit are proportional; the proportionality coefficient depends only on the conduit dimensions and the dynamic viscosity. The apparatus consists of a capillary tube connected to a pressurised, thermostatically controlled vessel.

One support on which all bench components are mounted.
Two capillary tubes.
One digital pressure gauge.
One glass thermometer.
One stopwatch.
Two graduated pipettes.
One thermostatically controlled, pressurised vessel with magnetic stirrer.
One temperature controller and one pressure reducer.
