Fluid mechanicsLaajuus (3 ECTS)

Objective

The student gets acquainted with fluid mechanics and with the structure of pumps, piping, blowers and channels so that one can design the piping systems and select pumps, and blowers. The student will also get familiar with computational fluid dynamics (CFD) to get ideas how phenomena of fluid mechanics can be approached with a numerical study.
