Entry Knowledge

Physics, mathematics and basic plumbing systems and heating.

Aims

  • Professional Knowledge: The student understands the fundamental physical principles of hydrostatics, hydrodynamics, and aerodynamics, governing equations for ideal and real fluid flows, characteristics of laminar and turbulent regimes, and the basics of CFD modeling.

  • Professional Skills: The student can calculate hydrostatic pressure, determine velocity and pressure distributions using Bernoulli's equation, quantify friction and local pressure losses in piping systems, and process fluid flow measurement data.

  • Professional Competences: The student is qualified to independently analyze hydraulic and aerodynamic phenomena to design, size, and evaluate piping networks and fluid transport systems in engineering practice.
