LABORATORY FOR MACHINERY AND TECHNICAL PHYSICS (UNIT 1)
Learning outcomes of the course unit
The purpose of the laboratory is to provide the student the knowledge and application methodology on two specific aspects of fluid machinery and energy systems: the importance of the experimental defintion of characteristic curves of fluid machines (providing the knowledge needed to properly develop and use of results) and plant design as a system of components (fluid machinery, heat exchangers, combustion chambers).
