液体 1,1,1,2,3,3,3-七氟丙烷 (HFC-227ea) 的粘度测量结果是在 263.15 K 至 343.15 K 的温度范围内沿着用校准的毛细管粘度计绘制的饱和线进行的。开发了一种改进的方法来校准粘度计和测量粘度。结果的不确定度估计不超过±3%。结果与温度相关。
Measurements of the viscosity of liquid 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) are reported over the temperature range 263.15 K to 343.15 K along the saturation line made with a calibrated capillary viscometer. An improved method was developed for calibrating the viscometer and measuring the viscosity. The uncertainty of the results is estimated to be no more than ±3%. The results were correlated as a function of temperature.
