The student knows and understands at an advanced level selected issues in the field of detailed knowledge, necessary to understand thermal, flow and thermodynamic processes occurring in environmental engineering.
The student is able to use the theoretical basis of thermodynamics for engineering calculations.
The student can plan and carry out advanced experiments as well as interpret the obtained results and draw conclusions.
The student can act creatively, cooperate in a group, assuming different roles in it.
The student is ready to analyze the content obtained from various sources and to critically assess the possibility of their use in professional work.
Assessment criteria
In the event of suspension of the functioning of the University, the following forms of crediting will be carried out with the use of distance education methods and techniques ensuring their control.
Lecture - written exam, 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.
Two dates of the exam are: examination in the basic examination session and resit in the resit 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 4 school hours without the excuse, next left hours must be justified, otherwise the student isn't ranking laboratory classes), carrying out all laboratory exercises and reports for every exercising by the team of students, as well as ranking fragmentary tests before every laboratory exercise to the pass mark (3.0).
For which ranking fragmentary test before laboratory exercise it is possible to gain 2 points, that is 16 points altogether.
To the A (5.0) the student should get 14.75-16.0 pts.
For the evaluation 4.5 13.25-14.50 pts.
To the B (4.0) 11.75-13.00 pts.
For the evaluation 3.5 10.25-11.50 pts.
To the C (3.0) 8.75-10.00 pts.
Result below 8,75 pts means a fail.
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 2 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 three tasks on the final test: the first one on ideal gas equation of state, the second one on steam, the third one on humid air for which it is possible to gain 2 points, that is 6 points altogether.
To the A (5.0) the student should get 5.5-6.0 pts.
For the evaluation 4.5 4.75-5.25 pts.
To the B (4.0) 3.75-4.5 pts.
For the evaluation 3.5 3.00-3.50 pts.
To the C (3.0) 2.00-2.75 pts., in addition doing one entire task is a condition of getting this evaluation, that is for example two tasks cannot be done in half or three tasks cannot be done in one third, and the like.
Result below 2 pts means a fail. The failure of one entire task 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.
