Viscosity Measurement using Ostwald's Viscometer (Amrita University)

Visit virtual Lab : http://sakshat.amrita.ac.in/VirtualLab/

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.

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

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

great thanks a lot very informative well can Ostwald viscometer by any means used to measure liquid soap viscosity which has viscosity of 1000 cps or even less please give details of viscometer range of Ostwald viscometer

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

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