What is density??
The relationship between mass and volume for a given substance.
What is viscosity??
The resistance of a fluid to flow, the slower a fluid flows the greater the viscosity. Basically how think or thin a fluid is.
What word tells how fast a liquid flows?
viscosity
What is a fluid??
a substance that has no fixed shape and yields easily to external pressure, a gas or a liquid.
what is archimedes principle?
result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.
Why do scientist use density to identify different substances??
Because, every substance has a different density.
difference between aerodynamics and hydrodynamics?
Aerodynamics deals with the motion of air. Hydrodynamics deals with the motion of water. They both come under Fluid Dynamics.
all liquids have the same viscosity
false
What is a laminar flow?
A laminar flow is a smooth pattern of flow
when a floating ice cube melts, the volume of water....?
is equal to the volume of the ice cube.
Ice will float in water, what does this tell you about the density of ice??
Ice is less dense than water so it floats.
What is buoyancy??
Buoyancy is a measure of the upward force a fluid exerts on an object that is submerged.
A liquid with high viscosity will flow slowly.
True
What is a turbulent flow?
A turbulent flow is an irregular, mixing flow pattern.
A balloon moving up in the air is based on the??
Archimedes principle
Different liquids and solids have....?
A different density.
What is compress??
To pack closely together (squeeze).
Honey has a greater viscosity than vinegar.
True
What is the difference between cohesion and adhesion?
Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances
What did Archimedes say after he discovered buoyancy??
Eureka!!
What is the formula to find the density of a shape??
The formula for density is d = M/V, where d is density, M is mass, and V is volume.
is oil more viscous than water??
Oil is more viscous.
solid
What is the difference between Fluid Mechanics and Fluid Dynamics?
Fluid mechanics studies fluids in either static or dynamic state. Fluid dynamics is a sub section of fluid mechanics. It only studies the effects of forces on moving fluids.
what is buoyancy??
The ability or tendency to float in water or air or some other fluid.
