0000001357 00000 n The results are employed to distinguish between conflicting data sets that already exist in the literature and that have inhibited accurate representations of the viscosity of this important fluid. The resulting equation of state is accurate from about 90 K to 625 K for pressures less than 70 MPa and was developed by considering PVT, second virial coefficient, heat capacity, and sound speed data. Chem. Fenghour and Wakeham [32] have presented an explicit model to calculate the viscosity … second, N-s/m2=Newton-second per square meter, kg/m-s=kilogram per meter per The results are compared with those of other authors. C., editor. 410 (TP 410). The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. The viscosity coefficients have been evaluated by measuring the electrical characteristics of a torsionally vibrating quartz crystal immersed in the liquid. References for gas viscosity The viscosity of carbon dioxide mainly affects the axial pressure transmission by generating flow friction. AddThis use cookies for handling links to social media.
