    • Compressibility
    • Surface tension
    • Toughness
    • Vapor pressure
    • Gas laws
  • Hydrostatics
    • 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.
