摘要

本研究的目的是根据密度随温度变化的实验数据确定生物柴油的热膨胀系数。为此，我们使用了一些热力学的基本原理。线性回归得到生物柴油的热膨胀系数为8.49 × 10-4°C-1，相关系数为0.9978。

Determinação de coeficiente de expansão térmica do biodiesel e seus impactos no sistema de medição volumétrico

The purpose of this study was to determine the coefficient of thermal expansion of the biodiesel from the experimental data of density as a function of temperature. For this, we used some fundamentals of thermodynamics. The value obtained for the coefficient of thermal expansion after the linear regression for biodiesel was 8.49 × 10-4 ° C-1, with a correlation coefficient equal to 0.9978.
