Viscosity Measurement using Ostwald's Viscometer - Amrita University

[@akhataybeh]

I understood it from your video, more than I did from the lab in the university ... Big THANKS :)

[@debaprasaddev8574]

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 .

?can i gate on report about the test pleas

@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 :)

Brilliant! This is so clear, thank you so much!

[@robythundathil]

really informative....and video is very clear....thnk u very much..

[@anasretube]

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

5 stars for this... nice explained

[@rahulkalwade]

i like your process..but unit is necessary to determine viscosity... which one unit is taken about it?

[@fahmylina123]

A very nice illustration and demonstration.

[@sphiedd]

what equation would i use if it was the relative viscosity?

Nice Presentation. Thank you

[@Rupack]

very much helpful :D :D contains a lot of useful infos :) thanks a lot !!

[@chrischeung5648]

If I am doing a test with oils, how much oil do you think I'll need to complete a viscosity test?

very helpful for my exam

very useful video

nice presentation.. but, still hard for me to undestand the languange.. I have to concentrate hard to figure out the english

+Shafira Dian Rizki Fitriana Nasution There is Closed Captioning on the video. If you look at the bottom right side of the video, you will see a small box with two letter "cc". Click on that box and the captions will appear. Some videos have multiple languages available.

+John Ferguson thank you, that helps ☺️

[@kasiviswanath4784]

why to dry the water with acetone

[@johnferguson7235]

+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.
