Status of the course

Course objectives

The aim of the course is to provide students with wide knowledge of basic thermodynamic principles related to their application in engineering.

Course enrolment requirements and entry competences required for the course

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, students are expected to:
1. specify and define the units of measurements of basic thermodynamic magnitudes and the state equations (for ideal and real gases)
2. specify and correctly interpret the basic laws of thermodynamics
3. specify and explain thermodynamic changes of the state of ideal and real gases
4. define and explain the processes of expansion and compression
5. define and explain maximum work, technical work and exergy
6. define and explain clockwise circular processes
7. define and explain irreversible processes (throttling, mixing of gases)
8. discern and analyse processes in devices used to obtain low temperatures
9. define and explain the principle of corresponding states, fugacity, partial molal quantities
10. apply the knowledge acquired to solving tasks related to changes of the state of ideal and real gases and liquids, compression processes, clockwise and counter-clockwise circular processes, and processes in technical heat exchangers.
