中文摘要 | 本文依據Riazi-Daubert經驗模式而提出一種簡便方法以推測32-212℉之間非極性及極性液體的表面張力。文中模式只須使用欲推測物質的正常沸點,比重及偏離因子以為輸入數據。以本文模式所得推測值經與數種有機液體的230個實驗值比較,其平均誤差為6.86%,而過去文獻上推荐的最佳共聯方法之一的Macleod-Sugden-Goldhammer其平均誤差則為13.82%。 |
英文摘要 | A simple method based on the Riazi-Daubert empirical model is presented for the prediction of the surface tensions of non-polar and polar fluids over the temperature range from 32 to 212℉. The proposed model requires only the normal boiling point, the specific gravity and the acentric factor for each component as input. Calculated surface tensions for diverse organic fluids produce an average deviation of 6.86% from experimental measurements for 230 points considered. The best all-around method of Macleod-Sugden-Goldhammer previously recommended gives an average deviation of 13.82%. |
