Online Data Resources in Chemical Engineering Education: Impact of the Uncertainty Concept for Thermophysical Properties

Abstract

We review the concept of uncertainty for thermophysical properties and its critical impact for engineering applications in the core courses of chemical engineering education. To facilitate the translation of developments to engineering education, we employ NIST Web Thermo Tables to furnish properties data with their associated expanded uncertainties. We present four pertinent examples for the engineering classroom and an application to research, which illustrate the practical combination of the concept of uncertainty with online data resources
