Summary |
---|
Hydromechanics deals with equilibrium forces in the fluid at rest and motion. Applies universally valid theorems of mechanics, i.e. the condition of balance of forces and moments, the momentum of change of momentum, the law of weight and energy conservation.
In hydrostatics, attention is focused on calculating the pressure and pressure forces in the fluid at rest. In hydrodynamics, the main topics is a steady and unsteady pipe flow, the discharge of fluid from the vessel through a pipeline or through a hole, a hydraulic pipeline calculation, water pump system solution, uniform flow in the channel, flow over a body and other applications. |
Learning Outcomes of the Course Unit |
---|
Students will be introduced to the application of conservation laws and force balance under steady and unsteady fluid flow. They will apply the obtained knowledge of general mechanics while learning about the continuum mechanics principles. They will conduct simple experiments to understand the theory. Having obtained the fundamental knowledge, they will be able to solve practical fluid flow mechanics problems, pressures and pressure forces under steady and unsteady flow in particular, and they will be introduced to more complex engineering problems solutions. |
