Learning outcomes

The student has theoretical knowledge covering issues of heat exchange in the basics of theoretical, computational techniques and measurement. The student has ordered theoretical knowledge covering issues of heat transfer engineering issues in environmental engineering. The student is able to formulate engineering problems in the field of heat transfer and resolve the issues calculation of heat transfer in environmental engineering. The student is able to select measurement tools and complete measurements of basic thermal parameters and equipment and technical systems. Student is able to use the scientific literature, the student understands the need for knowledge in the field of basic sciences to enhance the professional.

Assessment criteria

Methods and criteria of assessment

Lecture - written test, compound of 5 questions, for which it is possible to gain 2 points, that is 10 points altogether.
To the A (5.0) the student should get 9.5-10.0 pts.
For the evaluation 4.5 8.75-9.25 pts.
To the B (4.0) 7.75-8.5 pts.
For the evaluation 3.5 7.00-7.50 pts.
To the C (3.0) 6.00-6.75 pts.
Result below 6 pts means a fail.
According to Study Regulations PB grade will be held on two dates ie .: term base - the last class in the semester and term correction - during the examination session.

Laboratory classes - an attendance in classes is an essential condition of the credit (according to the study regulation of the Białystok Technical University it is possible to leave 3 school hours without the excuse, next left hours must be justified, otherwise the student isn't ranking laboratory classes), as well as ranking fragmentary tests before every laboratory exercise and carrying out all laboratory exercises and reports for every exercising by the team of students. Meeting above requirements means the pass mark (3.0).
Students which want to receive the higher evaluation than the pass mark are examined on 35 questions concerning the subject matter of laboratory exercises. Questions are earlier familiar to students, since they receive them at the beginning of the semester.
To the A (5.0) the student should answer all 35 questions.
For the evaluation 4.5 the student should answer 27 questions.
To the B (4.0) the student should answer 19 questions.
For the evaluation 3.5 the student should answer 10 questions.
Ranking laboratory exercises should be made before beginning of the examination session.

Classes - an attendance in classes is an essential condition of the credit (according to the study regulation of the Białystok Technical University it is possible to leave 3 school hours without the excuse, next left hours must be justified, otherwise the student isn't ranking classes), as well as ranking the final test to the pass mark (3.0).
There are five tasks on the final test for which it is possible to gain 2 points, that is 10 points altogether.
To the A (5.0) the student should get 9.5-10.0 pts.
For the evaluation 4.5 8.75-9.25 pts.
To the B (4.0) 7.75-8.5 pts.
For the evaluation 3.5 7.00-7.50 pts.
To the C (3.0) 6.00-6.75 pts., in addition doing three entire tasks is a condition of getting this evaluation, that is for example two tasks cannot be done in half with two entire tasks or three tasks cannot be done in one third with two entire tasks, and the like.
Result below 6 pts means a fail. The failure of three entire tasks is also indicating a fail.
Two dates of the final test are: test and resit.
The test and the resit should be made before beginning of the examination session.
