nur rahmayani : Thank you for your explain
This video is very attractive and help ful
anas ali : very helpful in my research! Thanks alot.
Ajaykumar suryanarayan Singh : Thank you so much❤
Andres Rivera : Buenas tardes.
Cordial saludo.
Les pido un favor, se daño un componente de la tarjeta electrónica de mi equipo Brookfield viscometer DV-E , el componente fue una resistencia y un Diodo, pero no se logra ver la referencia de ellos. Si me pueden hacer el favor y me pueden compartir los planos
Quedo atento a sus cometarios.

Ostwald's viscometer is a traditional viscometer to measure the viscosity of a liquid. It is a U-shaped glass tube. In one arm, the bulb A is connected with a fine capillary. The lower end of capillary is connected with a U-tube provided with a bulb B in the second arm. The bulb is necessary to maintain the hydrostatic pressure during flow of liquid. Through the capillary tube, the liquid flows with measurable speed. There are two marks C and D above and below the bulb A. The liquid flows under its own weight.
Ahmed Nasret : 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
RoseSheeps : Brilliant! This is so clear, thank you so much!
Amer Khataybeh : I understood it from your video, more than I did from the lab in the university ...

Sangeetha Bavan : Nice Presentation..... Thank you.... Please upload more experiments
sphiedd : what equation would i use if it was the relative viscosity?

Brookfield Viscometers, How to Take a Viscosity Reading

The Brookfield Dial Reading Viscometer measures fluid viscosity at given shear rates. Viscosity is a measure of a fluid's resistance to flow.
Modhusudan Mondal : What is size of the spindle size? What is the size of the spindle used?
R J : Good presentation
sankar chidambaram : Nice
Durai Mahi : I want tapioca starch all testing methods
1 tapioca starch viscosity
2.so2 test
3.nitrogen test
4.fibre test
5.ash test
Manish Gupta : Very nice
