Objectives

This course aims to acquaint students with the fundamental concepts of Thermodynamics and apply them to the main engine cycles and refrigeration, as well as to psychrometrics and combustion. Learning Outcomes: students should know how to analyse energy transformers cycles, psychrometric processes and combustion. First week: acquaintance and understanding of important parameters in the analyse of the main thermodynamic cycles; Rest of the semester: acquaintance with the energy transformers cycles and their performance. A psychrometric and combustion approach.

Eligibility for exams

According to General Evaluation Rules of FEUP

Calculation formula of final grade

The assessment of this course (uc) will be made as follows:.
Formula evaluation: Distributed evaluation with final exam. Two Moodle theoretica mini-tests during the semester bwith a weigh of 15% each, plus a final written exam with a weight of 60%, and the evaluation of the two laboratorial works each with a weight of 10%.

Resit exam is for the whole subject matter and is also composed of a therotical Moodle test (30% weight) and a written pratical test (60% weight), where the access to the written test requires a mark of 2.0/6.0 on the two Moodle tests. The laboratorial component must have been previously assessed, or the studant will loose 10% of the final mark.

Observations

For all examinations, the students can only take with them the book  "Termodinâmica para Engenharia" and tables of thermodinamic properties of substances. The studants that don't have the book can take four pages A4 written with information that the students think is necessary.
