level of course unit
First cycle, Bachelor
Learning outcomes of course unit
Through the “Dynamics” component, the students are able to:
• Analyze physical problems in the field of dynamics independently,
• Develop solution methods and devise solutions.
• Reduce technical systems of a mechanical nature to the underlying physical principles.
• Apply mathematical methods to solve physical problems.
• Independently identify problems in technical systems, develop physical models for solutions and estimate the feasibility of physical processes.
• Describe, present and pass on knowledge gained.
Through the “Hydromechanics” component, the students are able to:
• Describe the essential material properties of liquids.
• Determine and calculate the forces acting on geometric surfaces due to hydrostatic pressure.
• Calculate the momentum of simple geometric bodies.
• Apply and calculate the continuity and energy equations to simple hydraulic systems.
• Analyze simple systems of pipe hydraulics and calculate the occurring pressure losses, volume flows and flow velocities.
• Apply the impulse and twist laws to simple hydraulic systems and calculate the force effect of flowing fluids.
• Apply similarity laws to simple hydraulic systems.
