Annotation Study course 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, especially ones, that work in mobile devices, such as automotive and railway industry products are explained..
Study course explains how real fluid circuits work. Mostly pneumatic and hydraulic circuits for movement and force generation for mobile devices are viewed. Components of these circuits are analysed and properties of those components are viewed. Parameters and calculation principles of hydraulic circuits are shown..
