All other values will be re-calculated automatically. Just put your values (either imperial or metrical) in the appropriate fields below and press ENTER. The use of any of the calculators’ results is at the user’s sole risk. The calculator below is for informative purposes only. A tolerance of ☒0 is considered in IS:73 (2013) resulting in the corresponding absolute viscosity tolerance of ±400 Poise for VG20 bitumen and the subsequent range is 1600 to 2400 Poise.
#ABSOLUTE VISCOSITY ISO#
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. represents the absolute viscosity of 2000 Poise. These data is enough to determine kinematic viscosity at any other values of temperature and as well Viscosity Index. Several authors have offered empirically-derived correlations between viscosity and temperature for sludge. Расчёт индекса вязкости по кинематической вязкости`)Īny mineral oil is supplied with the specification of kinematic viscosity values at two different temperatures, usually at 40☌ and at 100☌ (or at 100☏ and at 210☏). The change in the viscosity of water (in mPa s) with temperature within the limits of 5 and 35☌ can, within an R2 value of 0.9995, be represented by the quadratic equation: (1) w 5.829 × 10 5 T 2 4.868 × 10 2 T + 0.00174. the Viscosity Index (VI) by the formulas specified in ASTM D2270 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ISO 2909 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ГОСТ 25371-2018 (`Нефтепродукты.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 interpolation calculator provided below is used to determine:
