Abstract

In this article we study the behavior of biodiesel viscosity from corn biodiesel, transesterified with methanol, in relation to temperature. These quantities were measured with capillary viscometers, from 20 ºC to 40 ºC. Measurement uncertainty was calculated. The behavior of viscosity with temperature is analyzed considering the estimated uncertainty.
