Course detail

Thermodynamic Engineering

FSI-KS1Acad. year: 2020/2021

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 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 properties of substances and their mixtures required for all engineering designs (density, viscosity, thermal conductivity, diffusivity, etc.) and determine thermodynamic state variables and their changes during various processes. Thermodynamic factors influencing processes in technological equipment and conditions of thermodynamic balance are analysed. The emphasis is put on consideration the behaviour of gaseous and liquid in real conditions.

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 mathematics (integration, derivation and simple differential equations solution).
Basic knowledge of thermodynamics (state behaviour of ideal gas and liquid, the first and the second thermodynamic laws, main thermodynamic quantities).
Basic knowledge of chemistry (stoichiometric calculations, concentration expressions,).

Co-requisites

Not applicable.

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

The credit is granted upon regular attendance on exercises and the students’ performance during exercises that prove that they have gained basic knowledge of the course during the semester and successfully written final test proving knowledge obtained from the course.
To gain the credit, a semestral paper has to be submitted. The topic of the paper is given during the semester and the main tasks of the paper are continually discussed during exercises.
The exam is the form of the written test. In the test, the student has to prove the ability to solve individually given tasks and demonstrate theoretical knowledge of the lectures’ topics. The overall evaluation also considers the results of the final credit tests and the level of the semestral paper.

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 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 processes in technological equipment.

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 attendance at lectures is recommended. 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 compulsory and checked.
