In the present work, thermophysical properties such as density (rho), dynamic viscosity (eta), refractive index (n(D)), and surface tension (sigma) of aqueous piperazine (PZ) solutions with mass fractions (100w = 1.74, 5.16, 10.35) have been measured from temperatures (298.15 to 338.15) K. All of...
