Science #1 - Understanding Fluids And Their Properties

Question 1

What is Viscosity?

Answer 1

The thickness of a fluid; Higher viscosity means slower/thicker flow.

Question 2

What is Cohesion?

Answer 2

When a fluid is sticking to itself because they’re attracted to each other. The thicker the fluid, the more Cohesion there is.

Question 3

What is Adhesion?

Answer 3

When a fluid is sticking to another object - the thicker the fluid, the more Adhesion there is.

Question 4

Hydrodynamic

Answer 4

Part of fluid dynamics - how liquids flow. Hydrodynamics works by applying physics, predicting how fluids flow, how pressure changes, and how forces act on objects in the fluid.

Question 5

Fluid Dynamics

Answer 5

Part of fluid mechanics - how fluids move. It works by predicting and explaining how fluids behave.

Question 6

Aerodynamics

Answer 6

Part of fluid dynamics - how gases move. Aerodynamics works by studying how air moves around objects and how that air movement creates forces like lift, drag, and thrust.

Question 7

Non-fluid

Answer 7

Substance that does not flow or take shape.

Question 8

Fluid Mechanics

Answer 8

Study of fluids at rest and in motion. Fluid Mechanics works by moving and how they push or pull on things around them, using physics and math to explain it.

Question 9

Types of Flow

Answer 9

Laminar and turbulent flow in fluid dynamics.

Question 10

Laminar Flow

Answer 10

smooth, consistent flow ↳ calm river

Question 11

Turbulent Flow

Answer 11

rough, choppy flow

Question 12

Flow Rate Formula

Answer 12

Flow Rate = Volume / Time.

Question 13

Temperature Effect

Answer 13

Higher temperatures reduce viscosity, increasing flow rate.

Question 14

Surface Effect

Answer 14

Surface texture affects fluid flow speed.

Question 15

Fluid Examples

Answer 15

Water, oil, blood, and syrup are fluids.

Question 16

Fluid Categorization

Answer 16

Classifying substances as fluids or non-fluids.

Question 17

Fluid Characteristics

Answer 17

Ability to flow: Fluids can change shape and flow under the influence of gravity or pressure.

Question 18

Flow Rate

Answer 18

How fast the fluid flows. The higher the flow rate, the faster and thinner the fluid is.

Question 19

Take the Shape of Their Container

Answer 19

Fluids do not have an affixed shape and will conform to the shape of the container they are in.

Question 20

Factors affecting flow rate

Answer 20

viscosity, temperature, surface type and force applied.

Question 21

Real World Example of Turbulent Flow

Answer 21

Whitewater rapids in a river.

Question 22

Example of Hydrodynamics

Answer 22

Fish swimming efficiently in the ocean.

Question 23

Example of Fluid Dynamics

Answer 23

Airplanes flying through the air.

Question 24

Example of Fluid Mechanics

Answer 24

Blood circulation in the human body.

Question 25

Example of Aerodynamics

Answer 25

Wind turbines generating electricity.

Question 26

Example of Cohesion

Answer 26

Raindrops sticking together.

Question 27

Example of Adhesion

Answer 27

Water sticking to a glass surface.
