Subject aims expressed by acquired skills and competences
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.

Summary
Fluid Mechanics 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.

Recommended literature:
Way of continuous check of knowledge in the course of semester
Credit:
Present form of study: 2 continuous tests, laboratory measurements with subsequent evaluation and processing of the protocol (3 tasks). The maximum number of points for the credit is 30, the minimum required for the credit is 18 points.
Combined form of study: An individual program covering 20 examples-15 points. Control online test (basic formulas and examples)- 15 points. The maximum number of points for the credit is 30, the minimum required number for granting the credit is 18 points.
Exam: the same form for both full-time and combined form of study
It consists of a written and an oral part. The written part in LMS contains 20 test multiple choice questions and five examples to solve. The maximum number of points is 40, the minimum number of points required for the oral examination is 20 points.
The oral part consists of two questions - hydrostatics, hydrodynamics. For each correctly answered question is 15 points. The student must demonstrate knowledge of both .
