Summary
Students acquire basic knowledge and awareness about currents and
transformational events above all in dynamic compressors and pumps. The
acquired knowledge in these subjects and in these given above is used in
complex ways for the theoretical calculation of the individual parts of
energetic machines. The goal of this subject is to give a specialised
background to graduates of VŠB - the Technical University, which will work as
designers, but above all as operators of energetic equipment. In addition to
this they must have their own economic and ecological approaches.
