Abstract

Uncertainties are an estimate of the reliability of a measure. They are intrinsic to any measurement process and have their origin both in procedural flaws as the own limitations of the instruments used for the measurements. Understanding how they spread is critical to the design of experiments, once that to minimize them we obtain more reliable data. This study provides a conceptual discussion about uncertainty and illustrates the application of the methodology in a simple experiment related to Fluid Mechanics in a Chemical Engineering course. The methodology used for the analysis of uncertainties was Kline and McClintock. Engineer Equation Solver software (EES) was used for the calculations.
