Hydrodynamics Flashcards
1
Q
What are the three main types of fluid flows?
A
Water: fluvial, lacustrine, marine environments.
Air: aeolian transport.
Water/sediment mixtures: debris flows, turbidites.
2
Q
What are the three important fluid properties?
A
Density (ρ, mass/unit volume), temperature (T), and dynamic viscosity (μ, pascal seconds, kg m^-1 s^-1 Nm^-2).
3
Q
What is fluid viscosity?
A
Measure of the ability of a fluid to flow; water = low viscosity, molasses = high viscosity; higher temperature = faster flow; viscous fluids flow by internal shear.
