Abstract:
The proposed rheological study for six vegetable oils which are: olive oil, coconut oil, almound oil, sesame oil, cottonseed oil and sunflower oil shows their non-Newtonian behavior. With the help of the Rheotest viscometer I determined the shear stress and then the dynamic viscosity. The analysis of the rheograms shows a decrease in the dynamic viscosity with the temperature and shear rate for the four studied vegetable oils.
