The viscosity index can be calculated using the following formula: where U is the oil's kinematic viscosity at 40 °C (104 °F), Y is the oil's kinematic viscosity at 100 °C (212 °F), and L and H are the viscosities at 40°C for two hypothetical oils of VI 0 and 100, respectively, having the same viscosity at 100°C as the oil whose VI we are trying to determine. That is, the two oils with viscosity Y at 100°C and a VI of 0 and 100 would have a viscosity of L … WebAn Investigation to Measure the Viscosity of Golden Syrup.
