- is familiar with the concept of different equations of state
- is familiar with the concept of vapour/liquid equilibrium for mixtures
- knows the definition of a partial molar property
- is familiar with the entities of fugacity and activity coefficients
- is familiar with calculation procedures of thermodynamic properties in computers

#### Skills

The candidate:

- can calculate problems involving the principles of conservation of mass and energy
- can calculate equations involving the entities of internal energy, enthalpy, entropy and Gibbs free energy
- can argue about strengths and weaknesses of different equations of state
- can calculate processes involving heat and power machines including ideal and non-ideal heat and power cycle calculations
- can calculate problems involving vapour/liquid equilibrium for mixtures and fugacity and activity coefficients
- can argue about the inherent limitations of energy transformations
- can argue about strengths and weaknesses of different ways of computing thermodynamic properties

#### General competence

## Course Description

The course consists of the following topics:

- The concepts of mass and energy conservation (1st law) and reversibility (2nd law) applied to closed and open (control volume) systems
- Thermodynamic cycles (e.g. thermal power plants, heat pumps, refrigeration)
- Exergy analysis and 1st and 2nd law efficiencies
- Relations between state functions and their derivatives
- Total differentials, partial differentials and their meaning
- Introductory description of thermodynamic energy functions (U, H, A and G), departure functions and thermodynamic reference states
- Selected volumetric equations of state for pure substances and mixtures
- Phase equilibrium in a pure substance, fugacity
- Calculation of vapor-liquid phase equilibrium in mixtures (dew point, bubble point and isothermal flash) by equation of state method and activity models

## Teaching and Learning Methods

Lectures and tutorials are used.

Lectures (based on textbooks) are used to facilitate knowledge and to give a basis for calculations. Demonstrations of calculation programs are also used as a basis for the students’ own calculations. Tutorials are used to develop calculation skills.

## Assessment Methods

Grading is based on an intermediate test which counts 30 % and a final exam which counts 70 % in the final grade.

In order to pass the course, the student must pass the final exam.

*Minor adjustments may occur during the academic year, subject to the decision of the Dean*
