Flashcards on Fluid Dynamics
Click on the flashcard to see the answer
What is fluid dynamics?
The study of how fluids behave and the forces acting on them.
What is a fluid?
A substance that can flow and take the shape of its container.
What are the two main branches of fluid dynamics?
Fluid statics and fluid mechanics.
What is fluid statics?
The study of fluids at rest or in equilibrium.
What is fluid mechanics?
The study of fluids in motion.
What is viscosity?
The measure of a fluid's resistance to flow.
What is Bernoulli's principle?
As the speed of a fluid increases, its pressure decreases.
What is Pascal's law?
Pressure applied to an enclosed fluid is transmitted equally in all directions.
What is Reynolds number?
A dimensionless quantity used to predict the flow pattern of a fluid.
What is surface tension?
The force that acts on the surface of a liquid.
What is laminar flow?
Smooth flow of a fluid with orderly motion in parallel layers.
What is turbulent flow?
Irregular flow of a fluid with chaotic and unpredictable motion.
What is drag force?
The force that opposes the motion of an object through a fluid.
What is streamlining?
Designing objects to reduce drag and improve fluid flow.
What is the equation for calculating pressure in a fluid?
Pressure = Force / Area
