Summary
Subject belongs to group of study subjects, that closely follows subject like Thermodynamics, Physics and Hydromechanics. Students acquire basic knowledge of energy transformation in combustion equipment, compressors, pumps, turbines or condensers. Students also develop creative thinking through theoretical calculations of these energy machines. Practical measurement of energy quantities at measuring laboratory lane are integral part of tutorial. Aim of subject is to form professional profile of graduate that will work as operator of these energy machines with knowledge of technical and also economical categories with minimal damage of environment.
