Org-unit: Maschinenbau
Displayed in timetable as:
FluidMech
Hours per week:
2
Language of instruction:
German
Min. | Max. participants:
- | -
Requirements and recommendations:
Basic knowledges in mathmatics and physics
Aim of the event:
In an huge number of technical processes fluid media move through machines and apparatus and lead to energie and mass transfer the whole facility was built for. The lecture supplies understanding for the phenomena connected with flow of fluids, particularly the momentum and energy transfer. The students should be made capable to perform simple calculations to this theme.
Target group:
chemistry,
Plastic technology,
Process technology,
Mechanical engineering and industrial engineering
