Fluid dynamics
Both liquids and gases are fluids because they can flow and deform continuously. This topic is part of Physics within Science & Nature. This page currently draws on 4 supporting questions, with answers and bonus facts available below.
Fluid dynamics trivia questions
Fluid dynamics studies the motion of what?
Answer: Liquids and gases
Bonus fact: Both liquids and gases are fluids because they can flow and deform continuously.
What dimensionless number is commonly used to compare inertial and viscous effects in a flowing fluid?
Answer: Reynolds number
Bonus fact: Reynolds number helps predict whether flow is more likely to be smooth and laminar or chaotic and turbulent.
Which equations are fundamental to describing the motion of viscous fluids?
Answer: Navier-Stokes equations
Bonus fact: The Navier-Stokes equations are central to engineering, weather modeling, aerodynamics, and many other fluid-flow problems.
Hydrodynamics is the study of the motion of what?
Answer: Liquids
Bonus fact: Hydrodynamics is the liquid-focused branch of fluid dynamics.
