Course detail
Thermodynamic Engineering
FSI-KS1Acad. year: 2018/2019
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.

Prerequisites
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).
Co-requisites
Planned learning activities and teaching methods
Assesment methods and criteria linked to learning outcomes
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 consists of a written and an oral part. In the written part, the student has to prove the ability to solve individually three given computation tasks. During the oral exam, the student will explain the solution of the computation and prove knowledge of the lectures’ topics. The overall evaluation also considers the results of tests written during the semester and the level of the semestral paper.

Aims
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.
