Abstract
Measurements of the viscosity of Liquid 1,1,1,2,3,3,3-heptafluoropropane (H FC-227ea) are reported over the temperature range 263.15 K to 343.15 K alon g the saturation line made with a calibrated capillary viscometer. An impro ved method was developed for calibrating the viscometer and measuring the v iscosity. The uncertainty of the results is estimated to be no more than +/ -3%, The results were correlated as a function of temperature.
