Fluids Test Definitions (2)

Question 1

Buoyancy

Answer 1

Tendency of an object in a fluid to rise or sink due to density differences with its surroundings.

Question 2

Density

Answer 2

Amount of mass contained in a given volume

Question 3

Flow rate

Answer 3

Measure of the speed at which a fluid flows from one point to another, determined by measuring the amount of fluid that flows past a given point in a given time.

Question 4

Pressure

Answer 4

Amount of force applied to a given area

Question 5

Compressibility

Answer 5

Property of being able to be compressed or made more compact

Question 6

Viscosity

Answer 6

Resistance of a fluid to flow

Question 7

Displacement

Answer 7

Occurs when something takes the place of something else

Question 8

Pascals law

Answer 8

Law that states that when force is applied to an enclosed fluid, the increase in pressure is transmitted equally to all parts of the fluid

Question 9

Buoyant force

Answer 9

Is the upward force that a fluid exerts on an object

Question 10

Archimedes Principle

Answer 10

Archimedes Principle states the upward, buoyant, force that is exerted on a body immersed in a fluid is equal to the weight of the fluid displaced by the object.
