Learning outcomes of the course unit
Knowledge of principals, terms, laws. Capability of solving of simple hydrostatic and hydrodynamic problems of ideal and viscous fluid. Knowledge of basics of fluid machines.
Prerequisites
Mathematics and physics on the level of the courses passed. Basic knowledge of differential and integral calculus.
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,
presence on the excercises.Student have to obtain classification not les than E on written tasks. The date of written tasks have to be specified at the begin of semester. Attending of all laboratory excercises. Writing of treatise about accomplished measurings duering laboratory excercises.
Examination.
The goal of examination is to check the students knowledge of laws used in hydromechanics and their application in practise.
Exam has three steps
1. step: test – checks the basic theoretical knowledge from hydromechanics.
2. step: examples – checks the ability to solve some concrete examples from hydrostatics and hydrodynamics.
3. step: oral exam – this part is not compulsory. It is used for the classification finishing.
Aims
The course deals with the basic theory and methods of the modern Hydromechanics as a rudiment of all the technicals.
Specification of controlled education, way of implementation and compensation for absences
Seminars and written tasks on the tutorials.
Presence on the laboratory tutorials.
