This study's objective is to determine the refractive index value of biodiesel by utilising the Lorentz-Lorentz mixing method to compare the refractive index values of diesel and biodiesel that are produced by combining jatropha oil, ethanol, and diesel. Additionally, the research will seek to determine the refractive index value of biodiesel. Detailed instructions and materials: For the purpose of producing one-of-a-kind mixes of biodiesel samples, the Lorentz-Lorentz mixing technique is utilised. The first group that we will utilise for this experiment is going to be biodiesel, and we are going to use a refractometer to determine the concentrations of ethanol, diesel, and jatropha oil in a variety of fuel blends. The frequency with which this technique is repeated is determined by the various ratios of blending utilised. Twenty samples are included in each of the groups, for a total of forty samples. The two-sample t-test with confidence levels of 80 percent and 95 percent using G power is utilised in order to evaluate various fuel blends. Group II employed diesel as their control, and they compared the refractive index values of the biodiesel mixture and diesel according to the blending ratio in order to form conclusions regarding the significance of the difference. For the biodiesel mixture, the refractive index value was 1.4285, whereas for the petroleum diesel mixture based on jatropha oil, it was 1.4055. This was the result of the experimental procedure. During the process of experimenting with biodiesel and diesel fuel mixtures, these equations were utilised. There are statistically significant differences between the two groups in terms of fuel type, with a significance value of p<0.05. The biodiesel attained a significant value of 0.001, and the results demonstrated that there are significantly different fuel types between the two groups. According to the findings, diesel fuel and biodiesel blends can have their refractive indices computed with a high degree of precision if the refractive index of each component is taken into consideration. In order to make an accurate prediction regarding the refractive index of diesel and biodiesel mixtures, the formulae can be used as a guide. [ABSTRACT FROM AUTHOR] |
