Chemical and Energetic Engineering
Mode of completion and Number of ECTS credits:
Exm (6 credits)
Course supervisor:
prof. Ing. Ľudovít Jelemenský, DrSc.
Learning outcomes of the course unit:
The student will acquire knowledge and skills in balancing the mass, energy and momentum through understanding and mathematical description of the physical mechanism of transport of substances, momentum and heat transfer in selected technological processes and equipment. At the same time will also control the groundwork for energy management media integrating material and energy flows.
