Rheology is a branch of science with multiple implications in numerous sectors of industry, also constituting a generous field due to its multidisciplinary character. Thus, solving a problem in rheology calls for knowledge from modern mathematics, physics, chemistry, chemical and mechanical engineering, and materials science. Driven by the appearance of new materials (plastics and synthetic fibers, varnishes and paints, detergents, adhesives, pharmaceutical and cosmetic products, biological materials, etc.)
Rapeseed ranks third in the world as a source of vegetable oil, after palm oil and soybean oil Through the exponential fit, we found a relation between the dependence of the dynamic viscosity on the temperature at different shear rates. The obtained correlation coefficients have values close to unity for all shear speeds to which the refined rapeseed oil was subjected. The found equation faithfully describes the non-Newtonian behavior of the studied oil in the temperature range.
For the studied oil, the correlation coefficients have values between 0.9725 and 0.9955.
