INVESTIGATION OF THE TEMPERATURE DEPENDENCE OF THE VISCOSITY COEFFICIENTS OF HYDROCARBONS

In the article, for the first time, the dependence of the viscosity coefficients of an organic mixture consisting of carbon and hydrogen, which are part of the most commonly used petroleum products in practice, on the temperature at atmospheric pressure was investigated and determined by experimental measurements and calculations using laws and formulas known from physics in the temperature range (300-380) K. The experimental setup was implemented by improving the classical the Stokes method, which determines the coefficient of dynamic viscosity of liquids at room temperature, atmospheric pressure. An automated installation has been assembled to measure the fall time and temperature changes of an aluminum ball falling under the influence of the Earth's gravity. Graphs of the temperature dependence of the coefficients of dynamic and kinematic viscosity of the studied samples are constructed, explanations are given
