INVESTIGATION OF THE INFLUENCE OF TEMPERATURE ON FUEL VISCOSITY COEFFICIENTS

The study of the temperature dependence of petroleum products at atmospheric pressure is of great practical and theoretical importance. Since the air temperature on our planet changes at long intervals, the study of the temperature dependence of the viscosity coefficients and kinematic viscosity characterizing the flow rate of fuel used as an energy source in automobiles, railways, and water transport contributes to improving the quality of technical work. In the article, as a model, the coefficients of dynamic, kinematic viscosity of diesel fuels DS (summer), DW (winter), often used in production and engineering, in the temperature range (20-170) 0 C at normal pressure are investigated. The design of the installation conducting experimental measurements has been improved on the basis of the classical Stokes method. The temperature dependence of the dynamic viscosity coefficient of the test sample was calculated by the Stokes formula in the temperature range every 100 C. And the effect of temperature on the kinematic viscosity coefficient was determined by dividing the dynamic viscosity coefficient by the sample density.
