Rules for evaluation and completion of the course

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.


Seminars and written tasks on the tutorials.
Presence on the laboratory tutorials.
