Syllabus
Examination methods: The exam takes place in writing and the students has a total of 2 hours and 30 minutes to do it.
It is divided into two parts: exercise + theory. The two parts have the same weight on the final vote.
Exercise: the student has to solve a numerical problem (he has 1 hour and 30 minutes).
Theory: the student has to illustrate three different topics, the first one concerning general thermodynamics, the second one concerning thermodynamic cycles and the third one concerning heat transmission (he has 1 hour).
Assessment criteria: The final vote is an average of 2 votes: respectively the votes of the theory and of the exercise. Both have to be sufficient. If the students have shown particular interest and good will, the exam could be passed even if one of the two parts (theory or exercise) is not fully sufficient. The average between the two votes must however necessarily be at least 18.

EXAMPLE: vote of theory 16, vote of the exercise 20: the exam is passed with final vote 18. Vote of theory 16, vote of the exercise 18: the exam is not passes
Course unit contents: Units of measurement systems: fundamental and derivative units, International SI system, Technical system, Anglo-Saxon system. Main conversion factors.

HEAT TRANSFER

Steady heat conduction: Fourier's postulate, the thermal conductivity of substances. General equation of conduction. Integration of the general conduction equation for a slab with or without internal heat source and for composite slabs.
