## MMI101 Fluid Mechanics

 Code MMI101 Name Fluid Mechanics Status Compulsory/Courses of Limited Choice Level and type Undergraduate Studies, Academic Field of study Mechanics, Mechanical Engineering, Machine Building Faculty Academic staff Ēriks Geriņš, Guntis Strautmanis, Kalvis Kravalis, Guntis Pikurs, Andris Priževaitis Credit points 2.0 (3.0 ECTS) Parts 1 Annotation Subject gives an overview of the basic questions about liquid and gas flows and the most sufficient calculation model choice. Different kinds of flow are viewed and various processes in nature and machine industry fluid circuits are explained. . Subject explains how real fluid circuits work. Mostly pneumatic and hydraulic circuits for movement and force generating are overviewed. Components of these circuits are analyzed and properties of those components are viewed. Parameters and calculation principles of hydraulic circuits are shown. Hydraulic circuits for movement generation are analyzed.. Goals and objectives of the course in terms of competences and skills The aim of the course is to give the knowledge about calculation principles for different kinds of flows at different circumstances. Knowledge about different pneumatic and hydraulic circuits and their components is given. During the training process students gain knowledge about theory of flow calculation, and main principles of hydraulic and pneumatic circuit work.They gain abilities to calculate and assess hydraulic and pneumatic circuits. After the course student is able to create hydraulic circuit for movement generation.
