Fluid properties

Question 1

One of the most commonly used measures , m/v

Answer 1

Density

Question 2

True or false, density isn’t proportional to pressure and inversely proportional to temperature

Answer 2

False

Question 3

Measure the fluid’s tendency to resist shearing force or to resist flow

Answer 3

Viscosity

Question 4

What are the 4 Fluid types

Answer 4

Clean Fluid
Dirty Fluid
Slurry
Steam

Question 5

Layers in the center of the pipe have the highest velocity, while the friction between the fluid and the pipe wall causes lower velocity near the pipe wall

Answer 5

Laminar

Question 6

Flow profiles often occur with low viscosity fluids. The low viscosity enables turbulent eddies ( whirlpools
) to form, which occur randomly in fluid stream

Answer 6

Turbulent

Question 7

Effect of the most important factors affecting fluid flow can be combined and expressed with a dimetionless, numerical value called ______.

Answer 7

Reynold’s Number

Question 8

Intertial force is divided by the viscous force

Answer 8

Reynold’s Number

Question 9

Rd < 2000

Answer 9

Laminar

Question 10

Rd > 4000

Answer 10

Question 20

T or F to the inside diameter of a process pipe does not remain constant throught the process

Answer 20

T

Question 21

Higher core velocity may be causes by either a reducer or an expander

Answer 21

Symmetrical profile disturbances

Question 22

Causes Fluids to flow across the diameter of the process pipe rather than parallel to the pipe
