About This Product
Liquid flows from the reservoir through the capillary, and students record the rate of flow against the pressure head read on the scale. Applying Poiseuille’s law to these readings and the tube dimensions gives the coefficient of viscosity of the liquid. Educational Instrument can arrange export supply of the Mayer's Viscosity Apparatus to Antigua and Barbuda, Uganda, Burundi, Sri Lanka and South Sudan.
