| COURSE DESCRIPTION |
Course objectives |
To gain knowledge about the basic unit operations in the process engineering through theoretical expressions based on the mass and energy balances. Students are also acquainted with the working principles of the most used devices and selection of their optimum working conditions regarding minimization of energy consumption and product quality. |
Course enrolment requirements and entry competences required for the course |
Enrolled in or passed the course Exercises in Transport Phenomena
Enrolled in or passed the course Transport Phenomena
Enrolled in or passed the course Exercises in Unit Operations |
Learning outcomes expected at the level of the course (4 to 10 learning outcomes) |
After passing the exam the student is expected to know:
- fundamental principles of mechanical and of heat and mass transfer operations,
- explain the laws that follow performance of individual operation,
- explain the influence of operating variable on each operation,
- explain their working principle of the most common used equipment for particular operation,
- for a given process, select the appropriate equipment,
- possible operating problems that may occur during operation performance. |

Grading and evaluating student work in class and at the final exam |
During the semester student may take the exam by two theoretical (oral) and two calculation (written) tests. Test passing score is 55%. After passing all tests the average score for oral and written parts is calculated and the grade of each part is determined by the following criteria: 55%-66% - satisfactory, 67%-78% - good, 79%-89% - very good, 90%-100% - excellent.
In the final grade theoretical part constitutes 67% of grade while written part 33%. Students who do not pass the partial exams have to take exam in the regular examination periods. Final grade is determined by previously notated criteria. |
