Determine The upper plate, which moves at 2.5 metre per sec requires a force of 98. The graphic curve will be updated as well. The upper plate, which moves at 2.5 metre per sec requires a force of 98.1 N to maintain the Speed. All other values will be re-calculated automatically. Temperature conditions: Above -18C Description: Most frequently. Just put your values (either imperial or metrical) in the appropriate fields below and press ENTER. It is especially recommended for new car engines. The use of any of the calculators’ results is at the user’s sole risk. The experiments were repeated at volume fractions of 0.05, 0.1, 0.2, 0.4, 0.6, and 0. The calculator below is for informative purposes only. In this work, an experimental investigation on the effects of temperature and concentration of nanoparticles on the viscosity of ZnOMWCNTs/engine oil (SAE 10W40) hybrid nanolubricant is presented. 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. These data is enough to determine kinematic viscosity at any other values of temperature and as well Viscosity Index. Assume that the kinematic viscosity of oil is 30 cSt and the specific gravity is 0.9. 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☏). From Table (1.5) for SAE 30 oil, 0.29 kg/(m. Dynamic viscosities of some fluids at 1 atm and 20C (unless otherwise stated). 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:
