Learning outcomes
This course aims at giving students the basic knowledge of Applied thermodynamics and Heat transfer.Its
goal is to allow the student to perform first law analyses on components and on systems operating on direct
and reverse thermodynamic cycles.Its goal is also to allow the student to perform heat transfer analyses on
simple systems operating at steady state with the method of thermal resistance
Program

Heat Exchangers.
Development of the examination
LEARNING EVALUATION METHODSThe assessment of the learning level consists of a written test divided into two parts: in the first part, the student must solve 4 numerical exercises relating to technological applications that have been discussed in class. In the second part, the student must answer 4 questions on theoretical topics chosen from among those discussed in class. The time available for the written test as a whole is 120 minutes. After the written exam, the student who has obtained a mark (sufficient or insufficient) may apply to the oral exam in which the topics covered in class will be discussed.
LEARNING EVALUATION CRITERIATo successfully pass the exam, the student must demonstrate, through the tests described above, to have assimilated the concepts contained in the syllabus and to be able to properly solve numerical exercises related to technological applications learned during the course.
LEARNING MEASUREMENT CRITERIAThe 4 numerical exercises are evaluated with a maximum total score of 60 points out of 100 (each exercise is given a maximum score of between 10 and 20 points, with a total of 60). The 4 theoretical questions are evaluated with a maximum total score of 40
FINAL MARK ALLOCATION CRITERIAThe vote in hundredths obtained by adding the vote gained in any exercise and theoretical question is converted in thirthyeths. To proceed to the oral exam (in the same session or in a later session) a minimum score of 14/30 is required. The Lode is given to those who, in addition to achieving the maximum score on the written test, demonstrate to master very well the subject.
