Course abstract

The aim of study course is:
• knowledge on economic use of machines and apparatus, process management with minimal material and energy consumption and maximum use of equipment capacity (3 written tests on theory);
• skills to calculate various processes and equipment parameters, to choose appropriate conditions for equipment operation, formulate and analytically describe information, problems and solutions, explain and argument the selected process parameters (3 tests on calculations, seminars);
• competence to justify necessary amount of energy and raw materials, to evaluate the technical and economical parameters of processes and their impact on the environment (defence of laboratory works).
