Entry knowledge
Knowledge of physical laws from thermodynamics, heat transfer, mechanics of fluids and optics.
Rules for evaluation and completion of the course
Course-unit credit requirements: attendance at exercises, handing in laboratory records. The evaluation consists of results from laboratories. The examination consists of written and oral parts.
The work in laboratories is checked by reports and by checking computer-based evaluation of visualization records.
Aims
Students will be made familiar with experimental and optical measuring methods in environmental engineering, heat transfer and mechanics of fluids.
Students acquire theoretical and practical knowledge and learn to work with experimental equipment and with computer systems for records evaluation.
