Hydraulics

FAST-BR004Acad. year: 2024/2025

The course provides students with information on fluid behavior and its influence on objects and equipment in hydrostatic and hydrodynamic systems.
The course deals with determination of effects of water on plane and curved surface and information on floatation of bodies.
Findings about flow and motion of water in pipe pressure systems and in systems with free water surface (i.e. flow in natural and artificial open channels). Hydraulics of water structures.
Steady non-uniform and unsteady continuously changing flow in open channels and pipes, filling and emptying of non-prismatic reservoirs and lock chambers. Shaft and lateral spillways, chutes, types of hydraulic jump and design of stilling pools.
Basics of model similitude in fluid mechanics. Selected chapters of object hydraulics and pressure systems hydraulics.
Practical aspects of groundwater flow, principals of continuity and deterministic. Assumptions accepted for ground water flow solution, simple water intakes, simple models of flow through a dam, solution of system of wells.
The findings are applied in computational and laboratory exercises.
