Measuring Olive Oil viscosity Using two methods stokes and poiseuille

n this research we measured viscosity of two kind of olive oil, using two methods. We assure of accuracy of the tow methods by using a standard of glycerine, which its viscosity at 21oC is glycerine= 13.5 p, after that we measured viscosity of olive oil, first kind of olive oil we obtained from local market in Lattakia city (best kind), and the other kind of olive oil we got it from burned olive trees which burned about October 2020
