Fluid dynamics
Definition
Fluid dynamics is the study of how fluids (liquids and gases) behave when they are in motion or at rest. It involves understanding concepts such as flow rate, viscosity, turbulence, and buoyancy.
Related terms
Viscosity: Viscosity refers to how resistant a fluid is to flow. Honey has high viscosity while water has low viscosity.
Bernoulli's equation: Bernoulli's equation relates changes in velocity and pressure for an ideal flowing fluid.
Reynolds number: The Reynolds number helps determine whether flow will be laminar (smooth) or turbulent based on factors like velocity and viscosity.
