This article presents the exponential dependence of the dynamic viscosity of temperature for a vegetable oil. In this article I studied coconut oil at temperatures between 40 and 1000C. The coconut oil studied at temperatures between 40 and 1000C and shear rates between 3 and 120 s-1 using a Haake VT 550 Viscotester used with the HV1 viscosity sensor. The exponential dependence is given by the formula.(7) By fitting we determined the values of the parameters η0, A and B at different shear speeds. The correlation coefficients have values close to the unit with the lowest value being at the shear rate 17.87 s-1 of 0.9615.
