Subject aims expressed by acquired skills and competences

Students obtain the knowledge of application of conservation laws and force balance in case of fluids at rest and in motion. They will realize simple experiments to understand the theory. They will be able to solve the fluid flow mechanics problems, pressures and pressure forces in case of steady and unsteady flow.

Teaching methods

Tutorials
Experimental work in labs

Summary

Hydromechanics deals with the forces balance in fluids at rest as well as in motion. Generally valid laws from mechanics are applied, i.e. force balance and momentum balance, law of momentum change, law of preserving mass and energy. Hydrostatics takes care about pressure and pressure forces calculations during fluid at rest and relative motion. Hydrodynamics investigates steady and unsteady flow of ideal and viscous fluids in pipe, liquid discharge from a tank through pipes and holes, hydrodynamic pumps, body drag forces and other applications.
