Objectives

Background: Thermodynamics requires and provides a solid knowledge of different methodologies for the prediction of volumetric and thermodynamic properties for pure fluids, as well as energetic needs in engineering processes.


Specific aims: To develop the knowledge to calculate thermodynamic and volumetric properties in different kinds of fluids, and also to use and discuss the application of the thermodynamic laws in the evaluation of heat and work in refrigeration and liquefaction processes, compressors and turbines.



Previous knowledge: Chemical Fundaments I and II, Calculus I and II and Algebra.

Percent distribution: scientific component - 70%
technological component - 30%

Learning outcomes:

1. Technical Knowledges: nuclear knowledges on engineering science, namely related to the concepts of classical thermodynamics, providing methodologies to calculate thermodynamic properties and energy balances for engineering processes.
2. Personal and Professional Aptitudes: resolution of engineering exercises - development of capacities to integrate previous concepts and knowledges.
