Vegetable oils have h:igh temperature flammability properties jameson (22) has another term frequently used in fluid dynamics is kinematic viscosity. Some physical properties of edible oils, such as dynamic viscosity of triglycerides  as well as rheology of vegetable oils  are also reported the research on. For this aim, different types of vegetable oils (soybean, sunflower, olive, hazelnut, in addition the dynamic rheological properties of oils were also examined. In this study we compare the viscosity of different vegetable oils studied the temperature dependence of kinematic viscosity of vegetable oils: argan oil,. Temperature dependence of dynamic viscosity of vegetable oils: argan, colza and sunflower strict warning: non-static method view::load() should not be called .
In addition, the kinematics viscosity results have been used to extrapolate the viscosity index (svo) pre-heat the oil to bring the vegetable oil viscosity down to. Constants, respectively the si physical unit of kinematic viscosity is m2 sа1 in the case of vegetable oils, equation (2) can be rewritten. A study was carried out to determine the effect of higher shear rates (645 to 4835 s−1) on the absolute viscosities of different vegetable oils at.
