Level of study:
Prerequisites for registration:
Assesment methods:
During the semester students will write four control computing tests. From each test they can get 25 points. To obtain classification A they must obtain at least 92 points, to obtain B at least 83 points, the C rating of at least 74 points, for the evaluation of D at least 65 points and E on the evaluation of at least 56 points. If the student does not reach the required number of points can be repeated once every topic of control computing tests. When it reaches the required minimum number of points from two subjects, a student may attend the exam. In this case, the exam consists of computing part and theoretical part. In case of 56 or more points during the control computing tests, calculating part of the exam is eliminated. The theoretical part of the exam is in writing form and the student must obtain at least 56% points from correct answers.
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.
