SAE 15W-40. This information is used to improve the website. Temperature differences of, for example, 10°C do not lead to identical number jumps in viscosity changes. The use of any of the calculators' results is at the user's sole risk. The viscosity index (VI), which is calculated with the aid of kinematic viscosity measured at 40°C and 100°C, is used to describe an oil’s viscosity-temperature behaviour. (The calculator on this site is for informative purposes only and we make no claims as to the accuracy, completeness or fitness for any particular purpose of the results produced by our calculators. lower limit for calculation: -150 C, 1 bar upper limit: 1000 C, 1000 bar . The physical principle of measurement is based on the rate at which a fluid flows under gravity through a capillary tube. Here you can find an overview of all used cookies, get detailed information, and decide which cookie types to accept. Online Water Viscosity Calculator. The interpolation calculator provided below is used to determine: the kinematic viscosity values, depends from temperature, calculated by the formulas specified in ASTM D341 – (‘Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products’); the Viscosity Index (VI) by the formulas specified in ASTM D2270 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity … Viscosity – the physics hypertextbook. Given two known temperature-viscosity points, the viscosity of a liquid can be calculated for a target temperature. Calculate the viscosity at a given temperature, when the viscosity is known at two temperatures. Calculate density and viscosity of glycerol/water mixtures. Viscosity - OELCHECK.
