  • Home preparation for classes - 30 hours per semester
Learning outcomes
The subject is aimed at presenting the fundamentals from the processing engineering. The course provides theoretical background for other technological subjects. Students utilise obtained knowledge for analysis, modeling, optimization and automatic control of technological processes according with minimization of power costs, saving of chemical agents and reduce of waste production in technological processes.
The student has knowledge about transport of heat, mass and energy, is able to do simple balance calculations and calculations concerning flow of the fluid in pipes. Student is well oriented in required literature and can use requested thermodynamic data and performs successfully calculations for the proposal of technological equipment, their dimensions, and also is able to do calculations for optimization of technological processes while keeping the lowest possible cost.
Prerequisites
Knowledge of subjects Mathematics, Physics and Chemistry.

Assessment methods and criteria
Oral examination, Written examination, Analysis of works made by the student (Technical products)

Attendance: obligatory 80% participation at exercises. Credit: passing the final written test and laboratory part. Examination: knowledge of the curriculum content already dealt with, oral exam. The result of a subject examination is expressed on a six-point scale: A "výborně" (i.e. "excellent"), B "velmi dobře" (i.e. "very good"), C "dobře" (i.e. "good"), D "uspokojivě" (i.e. "satisfactory"), E "dostatečně" (i.e. "sufficient"), F "nedostatečně" (i.e. "fail").
