For instance, an SAE 90 gear lube is comparable in viscosity to an SAE 50 or SAE 40 engine oil. Most oil labs test industrial fluids at 40 and 100 degrees C. By using these two parameters, you can calculate the viscosity index and extrapolate the viscosity at whatever in-service temperature the … The SAE (Society of Automotive Engineers) scale shows the viscosity of oil at both hot and cold temperatures. You can calculate pre-filled values of oil classified by ISO 3448 with grades VG22, VG32, VG46 or VG68 (at viscosity Index = 100) or enter specific values for any other oils. Calculate viscosity at a given temperature, when viscosity is known at two temperatures. Engine Oil SAE 15W-40 - kinematic viscosity and density over temperature, Engine Oil SAE 10W-40 - kinematic viscosity and density over temperature, Engine Oil SAE 10W-60 - kinematic viscosity and density over temperature, Engine Oil SAE 5W-40 - kinematic viscosity and density over temperature, Engine Oil SAE 0W-30 - kinematic viscosity and density over temperature, Engine Oil SAE 30 - kinematic viscosity and density over temperature. The main requirements for an engine oil are defined temperature-viscosity properties, protection against wear and corrosion, keeping the engine clean, holding particles like soot or abrasives in suspension, yield strength under compression and many more. But the engine and gear oil viscosity overlap. These data is enough to determine kinematic viscosity at any other values of temperature and as well Viscosity Index. 10 represents the proposed governing equation in which four coefficients are used to correlate the viscosity of heavy oil as a function of temperature … The viscosity at the target temperature is calculated when you click the 'calculate' button… were obtained for different temperatures, vs. temperature: a = f(T), b = f(T), c = f(T), d = f(T) (see Eqs. Air - Dynamic and Kinematic Viscosity . Engine oils are generally formulated oils. However, no practical theory exists for the calculation of these properties for heavy oil at elevated temperatures.

Just put your values (either imperial or metrical) in the appropriate fields below and press ENTER. 11 through 14]. Put them in the table above and find the value of temp at any value of viscosity. The MRC Engineer's Handbook states, "In general, the oil viscosity should be about 100 Saybolt Universal Seconds (SUS) at the operating temperature." Calculate viscosity … temperature %o viscosity tests were performed at one time, with two different viscometers. Amazing tool! As the temperature … Hydraulic manifold material selection chart, the kinematic viscosity values, depends from temperature, calculated by the formulas specified in, the Viscosity Index (VI) by the formulas specified in. "State system for ensuring the uniformity of measurements for the density of oil. A similar approach was used to develop a simple equation for the variation of the Heat Capacity or Specific Heat of crude oil as a function of API gravity and Temperature. Consequently, a correlation must estimate these values under different temperatures (Miller 1995). They consist of mineral, semi- or fully synthetic base oil (base stocks) plus a varying number and amount of additives. 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 viscosity of a liquid as a function of temperature can be approximated with the … Andrade’s method is based on the observation that the logarithm of viscosity plotted vs. reciprocal absolute temperature forms a linear relationship from somewhat above the normal boiling point to near the freezing point of the oil, as Fig. Formulas are taken from Russia's GOST R 8.610-2004.
