| Abstract: | The viscosity and surface tension coefficient of castor oil are measured with falling-ball and pull-out method respectively. Based on steepest descent method,the code FIT is developed to automatically search for the optimal parameters by fitting the measured experimental data. Then the empirical formula is obtained to describe the relation between viscosity and surface tension coefficient of castor oil. |
