Hydrodynamics 1
Course description
The course is compulsory for the second year students at the department of mechanical engineering. In this lecture, the students will learn the fundamentals of fluid mechanics. The lecture consists of basic properties of fluids, static and dynamical aspects of fluids. In addition, dimensional analysis will be taught with examples.
Purpose of class
1. To learn the basic knowledge on fluid properties (continuity, density, viscosity, and surface tension).
2. To learn the fundamentals of fluid statics (absolute/gauge pressure, manometers, Pascal’s law, pressure distribution, forces acting on a solid surface immersed in liquid, buoyancy, Archimedes' principle).
3. To learn the fundamentals of fluid dynamics (different types of flows (steady/unsteady, viscous/inviscid, laminar/turbulent), stream/path/streak lines), flowrate and hydrodynamic conservation laws (continuity equation, Euler’s equation of motion, Bernoulli’s theorem, Torricelli's law, Pitot/ Venturi tubes, momentum theorem).
4. To learn the dimensional analysis (basic/derived quantities, Buckingham’s pi-theorem, similarity parameters).
5. To learn the applications of the above concepts to fluid flow problems.
Goals and objectives
1. To understand the concept of fluid and to be able to explain the properties of fluid.
2. To understand the hydrostatic forces acting on a solid surface immersed in liquid and to be able to calculate them in a specific situation.
3. To understand the basic equations of the conservation laws (continuity equation, Euler’s equation and Bernoulli’s theorem, momentum theorem) and to be able to apply them in a specific problem.
4. To understand the concept of dimensional analysis and to be able to apply it in a specific situation.
