# Experimental dynamic and absolute viscosity

The dynamic viscosity deviation (?ν) values of each mixture are calculated using the following equation,equation(7)Δν=ν−x1ν1+x2ν2where ν1 and ν2 are the dynamic viscosities of pure components, and x1 and x2 are the L-690,330 factions of the EDA as component 1 and BDO as component 2.

Experimentally acquired ?ν values for the binary system at T = (293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K are listed in Table 7. According to Eqs. (5) and (6), the values of the parameters Ai together with the standard deviation σ are listed in Table 8. The dependence of dynamic viscosity values at various temperatures was plotted in Fig. 7.
