Unified low-parametrical equation used to calculate the viscosity coefficient of argon

Low -parametric equation for calculating the viscosity coefficient of nitrogen in liquid, gas and fluid states

“…Different correlations and models are developed and allow us to describe reference and experimental data on viscosity in a wide range of parameters of state. Using the modified equation [7,8] to calculate the viscosity coefficient, the equation was obtained to describe the viscosity of nitrogen in a wide range of the state parameters. In this case, the dependence of the excess viscosity  (T,  ) on the internal energy density is taken into account (figure 1).…”
