Poiseuille’S Viscosity Apparatus

Poiseuille's law is used to measure the viscosity of liquids by observing the flow through a capillary tube under a known pressure difference. This apparatus helps in determining the resistance the liquid experiences while flowing through the tube, and from this, the viscosity can be calculated. Consist of : · Capillary Tube: The uniform bore of Borosilicate glass is used, even a slight deviation could significantly alter the results.
