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: - 1st Test, T1, required, on a date to be communicated to students; this test will represent 50% of the final grade and shall be approximately half of the program the uc; - 2nd test, T2, include the subjects after the T1; this test will also have a weight of 50% of the final grade - final examination, EF, the  be performed simultaneously  with the 2nd test. Any student may choose to perform this test as an alternative to 2nd test; the EF includes all subjects of the uc; - recourse test, ER, will be performed by students who have not obtained a minimum score in any of the tests, T1 or T2, or who have not had an average of 10 values in both tests or examination, and further to improve the classification. This examination also includes all matter. Each test, EF and ER consist of a theoretical part to be held in the Moodle platform - American type-test (6 points) and a practical part with  realization of problems (14 points). > All tests will last for 2h: 30min. The final mark, CF, is obtained by: CF = (mark T1 + mark T2) / 2 or CF = mark of EF or CF = mark of ER.

Observations

For the final examination 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 takes four pages A4 written with information that the students think is necessary.
