The course aims to provide students with the fundamental knowledge to understand the basic principles of thermodynamics, energy conversion and utilization processes, heat transfer, and psychrometry, as well as the skills necessary to connect theoretical knowledge to the most common engineering applications.
Mathematical Analysis and Physics and Physics are required.
The course is delivered through theoretical lectures and classroom exercises, the latter aimed at deepening and reinforcing the topics covered during the lectures.
The exam consists of a written test, which includes solving numerical problems, and an oral test on the topics covered during the course.
The assessment aims to evaluate whether the student has acquired knowledge and understanding of the topics covered, as well as interpretative skills and independent judgment in practical cases. The student must also demonstrate communication and argumentation skills sufficient to convey their knowledge effectively to the examiner.
A passing grade will be awarded when the student demonstrates knowledge and understanding of the main topics, at least in general terms, and shows adequate skills useful for analysis of practical cases.
The final grade will be assigned according to the following evaluation criteria:
30 - 30 cum laude: complete, in-depth, and critical knowledge of the topics; full proficiency of technical language; comprehensive and original interpretative ability; full capacity to independently apply knowledge to solve the proposed problems.
26-29: complete knowledge of the topics; excellent proficiency of technical language; comprehensive and effective interpretative ability; good capavity to independently apply knowledge to solve the proposed problems
24-25: good knowledge of the topics; good proficiency of technical language; correct and confident interpretative ability; able to correctly apply most of the knowledge to solve the proposed problems
21-23: adequate knowledge of the topics but lacking full mastery; satisfactory command of technical language; correct interpretative ability; limited capacity to independently apply knowledge to solve the proposed problems
18-20: basic knowledge of the main topics; basic knowledge of technical language; sufficient interpretative ability; ability to apply only the most essential acquired knowledge to solve the proposed problems
Not-sufficient/fail: the student does not possess an acceptable level of knowledge of the topics covered during the course.
