Temperature-dependent viscosity correlations of vegetable oils and biofuel–diesel mixtures

Viscosity correlations of peanut, soy, sunflower, waste vegetable oil and its biofuel mixtures with diesel are presented based on three suggested equations. Calibrated capillary viscometers are used for measurements. Temperature is changed between the range of 20 °C and 120 °C. Correlations show small standard errors based on the method of curve fitting.
