The article substantiates the necessity of a specific form of the equation of state having simple and easy-to-use expressions that allow calculating the elastic properties of motor fuels quickly and with sufficient accuracy. An easy-to-use method is proposed for calculating the constants for the chosen form of the equation of state and presenting them in the form of expressions reflecting the temperature dependence of the constants. Based on the literature sources containing experimental data on the selected parameter - the speed of sound, a method is proposed for increasing the accuracy of the calculation by introducing universal coefficients reflecting the nonlinear effects of temperature and pressure for each considered liquid. The possibility of applying the developed methods of searching for constants of the equation of state, as well as increasing the accuracy of calculated data for a number of fuels, calibration and other technical liquids is demonstrated. |
