Fisica Tecnica (GEST)
Engineering Physics Francesco Corvaro
Basic knowledge of Calculus, Mechanics, Electricity and Magnetism.
KNOWLEDGE AND UNDERSTANDING:
The course allows students to acquire the basic knowledge related to the principles of applied thermodynamics, heat transfer and air treatment. This studies, by integrating the knowledge acquired in physics courses, will constitute a deeper base that will increase the knowledge of the thermo-mechanical sector, so that the student will acquires a better awareness of the wider multidisciplinary context of engineering, with a clear reference to the aspects connected with systems and technologies of production and energy conversion and of air-conditioning systems.CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
In order to acquire the fundamental tools and the basic elements to understand the thermodynamic processes, the heat transfer mechanisms, that allow the student to address problems related to practical applications: operation mechanisms of heat exchangers, of the cooling systems. The student must be able to understand the causes of technological behaviors already analyzed in other courses that are commonly addressed in engineering practice. This ability will be used through a number of vocational skills, such as: 1. the ability to understand the various thermodynamic cycles; 2. the ability to identify the heat exchange mechanisms; 3. the ability to understand the issues associated with the humid air treatment.TRANSVERSAL SKILLS:
The execution of shared classroom exercises, will help students to improve either the level of working independence, and the ability to communicate that also stems from the teamwork, and the ability to learn independently and to draw conclusions

Development of the examination
LEARNING EVALUATION METHODS
The assessment of the level of learning consists of an oral exam during which the student must answer questions related to the topics covered in class. The duration of the test will be the maximum of 30 minutes.
LEARNING EVALUATION CRITERIA
To successfully pass the exam, the student must demonstrate, through the test described above, to have assimilated the concepts contained in the program
LEARNING MEASUREMENT CRITERIA
Normally the student must answer to three different questions. Each question has a maximum score of 10 points.
FINAL MARK ALLOCATION CRITERIA
The final grade will consist of the sum of points obtained by the student in each question. The Lode is given to those who, in addition to achieving the maximum score, demonstrate to master very well the subject.
