Thanks to Amrita Lab for providing audio visual demo for HOW TO MEASURE VISCOSITY using U-Type Ostwald Viscometer . The English voice was very clear and easily understandable. It is simple but very useful tool with very nominal cost and effort. I must appreciate for the kind effort of Amrita Lab. Millions of students and researchers will be benefited from this .
@rahulkalwade you can measure it by poise or stoke depending on the equation you may use .. if u want it in poise then : viscosity = k*t*density in stoke : viscosity = k*t k is the instrumental constant , which you can eliminate by knowing the viscosity of a liquid and the calculate the viscosity of the unknown by a ratio .. hope you understand though it's kinda late :)
I am some confused, please help you called n2 as the absolute viscosity of the liquid. I knew that the capillary tube is to measure the kinematic viscosity not absolute. also, I found some article about the Ostwald's viscometer, and in such article they represented the n2 as the viscosity coefficient not as the absolute viscosity, could you please illustrate or send me a link to understand what is actually the n2 refers to? and what is definitely the viscosity coefficient ? thanks

+Kasi Viswnath The acetone breaks the adhesion between the glass surface and the water molecules. When the acetone is poured out, all of the water is removed. They the acetone evaporates leaving no residue. Pure alcohol can also be used but it works in a slightly different manner. It is eqauly effective.
