Assesment methods and criteria linked to learning outcomes
Course-unit credit: Demonstration of concurrent study of lectured topics and efforts to use the knowledge from lectures in controlled application to simple tasks in the area of design of functional parts of turbomachines. Credit is conditioned by successful completion of the semester test.
Examination: The knowledge of used physical laws and their application in individual types of turbomachines is tested. Structural design of basic functional parts of turbomachines and connection of constructional design and used properties of these machines. Relation of working conditions of turbomachines and their design.
The exam is written, supplementary questions are oral.
Semestral exam.

Aims
The course objective is to show students which measures is necessary to take for realisation of physical intention in a real machine and how is the construction of a given machine influenced by changes of conditions (type of medium, demanded power, pressure, temperature etc.) On the other side, students will learn how selected construction variant determines attributes and characteristics of a machine.
