Fluid Mechanics
Fluid Mechanics
Data is displayed for the academic year: 2025./2026.
Course Description
Teach students about the forces and pressure distribution in a resting fluid. To introduce students to the basic laws of fluid dynamics and they explain the application of those laws in cases of 1D flow. To teach students to apply the basic laws of fluid dynamics to the hydraulic machinery, and to predict fluid flow in pipelines.
