Abstract
Viscosities and densities of polyvinyl pyrrolidone + Water (PVP / H2O) mixtures were measured at several temperatures between (288.15 and 313.15) K under atmospheric pressure. The measured compression factor was satisfactorily correlated by a simple third-order polynomial with respect to temperature. The adjustment parameters are determined and presented. The comparison of correlated and experimental results indicated the applicability of the proposed model for compressibility factor predication of (PVP / H2O) mixtures.
