About This Product
In Poiseuille flow a liquid moves steadily through a narrow tube, and the loss of head along the tube depends on the viscosity of the liquid. On this viscometer students measure the flow rate and the loss of head to find the dynamic viscosity and see how it changes with temperature. The same readings are used to study shear stresses in viscous liquids and friction forces in laminar flow in tubes.
