Summary
The course summarizes basic principles and basic definitions of fluid mechanics and deepens the physical knowledge of mechanical, electrical and thermal properties of fluids. It includes hydrostatic and hydrodynamic fluids, fluid flow, physics similarity theory, and flow visualization methods, and allows the analysis of fluid phenomena from physical physics perspective. Issues related to liquid fuels, fluid movement in biological systems, and fluid rays issues are discussed. Simple relationships describing physical phenomena for calculating flow parameters are applied. Emphasis is placed on understanding the differences in fluid and fluid behavior, particularly in terms of flow, discharge, divergence in the environment of fluid flow, and energy loss. The effects of special types of environments on the behavior of fluid flow are analyzed. The aim is to teach students to use physical principles in the search for sources of improvement of the structure of devices working with liquids and to analyze selected phenomena in relation to their application in technical practice.
