- Hydrostatic pressure
- Forces on horizontal and vertical plates, dams
- Hydrodynamics of ideal (frictionless) fluids
- Bernoulli equation
- Applications of Bernoulli's equation to frictionless pipe flows
- Hydrodynamics of real fluids
- Hydrodynamic parameters
- Characterization of flow conditions (laminar, turbulent)
- Bernoulli equation with friction losses
- Real pipe flows, drag laws, local losses (fittings)
- Channel flows
- Qualitative description of flow conditions
- Manning-Strickler flow formula
Previous knowledge: Mathematics, Physics, Mechanics I and II
For the lecture a reprint (approx. 100 p.) and for the exercise a collection of exercises are available. Furthermore, examination papers with overviews of the results are available.
The lecture is recognized together with Hydromechanics II after successful participation in the exam with 3 credits.
