Prerequisites:

The students should have acquired the basic knowledges of the physics and differential calculus. 
Target skills and knowledge:

The educational goal is to provide the basics knoweledge of the applied thermodynamics and heat transfer processes, presenting realworld engineering examples, so that students can get an idea of how thermodynamics and heat transfer are applied in engineering practice. The acquired notions are applied to the analysis of engineering cycles and thermal plants. 
Examination methods:

he 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.
Each part must be at least with vote 16 and the average of the two votes must be 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
