Learning outcomes
|
The course deals with the basic theory and methods of the modern Hydromechanics as a rudiment of all the technicals.
The course presents the basic theory, properties and principal equations of hydrostatics and hydrodynamics as a starting point for analysis of both elementary and advanced hydraulics machines, mechanisms, hydraulic transporting systems, ducts, waterworks, etc. Knowledge of principals, terms, rules and elementaries of solving of simple hydrostatic and hydrodynamic problems of ideal and viscous fluid. Knowledge of basics of fluidic machines and surge.
