Course detail
Thermodynamic Engineering
FSI-KS1 Acad. year: 2016/2017 Winter semester
The course “Engineering Thermodynamics” is part of theoretical basis of process engineering. Students will gain basic knowledge necessary for resolving practical tasks connected to material and power evaluations of physico-chemical processes and designing mechanical-technological systems in chemical, manufacturing and power industry or waste processing technologies. This course introduces students within one semester with methods and procedures used to describe state behaviour of gases and liquids, determine physico-chemical properties of substances and their mixtures (density, viscosity, thermal conductivity, diffusivity, etc.) and determine thermodynamic state variables and their changes during various processes. Thermodynamic factors influencing physico-chemical processes and conditions of thermodynamic balance are analysed. The emphasis is put on consideration of real behaviour of gaseous and liquid systems.

Learning outcomes of the course unit
The course’s aim is to familiarize the students with regularities during physico-chemical processes and learn them to perform mass and energy balances of these processes. The gained knowledge and skills have a great importance for a process engineer’s work.
Prerequisites
Basic knowledge of chemistry (stoichiometric calculations, concentration expressions,).
Basic knowledge of thermodynamics (state behavior of ideal gas and liquid, the first and the second thermodynamic laws, main thermodynamic quantities).
Basic knowledge of mathematics (integration, derivation and simple differential equations solution).
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Course-unit credit requirements: active participation of students in exercises and working out a term project solving one of the main problems of the course. The examination consists of both written and oral parts. At the examination students demonstrate acquired knowledge.
Aims
The course’s aim is to introduce the students to basic thermodynamic regularities of physico-chemical processes and learn them to perform basic mass and energy balance of these processes.
The course introduces students to wide range of physico-chemical substance properties important for balance, hydraulic, thermal and diffusion calculations of process equipment. The gained knowledge will enable the students to understand the influence of working conditions on the results of physico-chemical processes.
Specification of controlled education, way of implementation and compensation for absences
The course is taught through lectures in a classroom with suitable presentation equipment. The students have access to support texts in electronic form. The exercises are carried on in given classroom and follow the topics of the lectures. The attendance at exercises is checked.
