The viscosity-temperature coefficient for coconut oil can vary by a factor of 10 depending on the temperature. The viscosity index obtained by the graphical method is much higher than that obtained by the other methods. Viscosity index obtained with the calculator program is 99,39% lower than that obtained by equation (1). The measurements were carried out at 40± 0.1 and 100± 0.1☌, according to the recommendation of ASTM D2270. Viscosity index of a coconut oil was determined using a set of Schott Ubbelohde-type viscometers selected according to the values of their constants, so that the margins of the uncertainty, inherent in the Hagebach-Couette correction, does not exceed the error allowed for the measurements. ![]() The viscosity-temperature coefficient was calculated from the measured viscosity at 40☌ and 100☌. Viscosity index calculation was performed with a computer program using kinematics viscosity at 40☌ and 100☌. ![]() Viscosity index was calculated from the measured viscosity at 40☌ and 100☌ using ASTM Method D 2270 and was graphically determined using ASTM D 341. In this paper viscosity index of coconut oil was determined using three methods. ![]()
