Learning outcomes of the course unit
Deep knowledge of principles and use of hydraulic machines. Students will be able to propose a design of hydraulic machines.
Prerequisites
Basic knowledge of hydromechanics, especially of parts with respect to impeller pumps and reaction turbines.
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
Solution of tasks within the practicals. The written exam testing the knowledge of the subject-matter. ECTS evaluation.
Aims
The aim of the course is to make students familiar with different types of hydraulic machines and equipment used in industry, in pumping stations, sewage treatment plants, in steam, nuclear and water power stations and which are used as elements in building machines, machine tools, as well as in robotics.
Specification of controlled education, way of implementation and compensation for absences
Participation in practicals is compulsory. Absence may be compensated for via special tasks set by the teacher.
