Chapter 9

Question 1

five functions of the reservoir

Answer 1

• hold fluid
• separate entrained air
• traps contaminants
• dissipate pressure pulse
• provides cooling

Question 2

three types of line used for pressurized fluid

Answer 2

pipe, hose, and seamless tubing

Question 3

pipe

Answer 3

• sized normally

- types: schedule 40, schedule 80, schedule 160, and double extra heavy (higher pressure rating)

Question 4

hose

Answer 4

sized by inside diameter

Question 5

tubing

Answer 5

sized by outside diameter

Question 6

lines sized on maximum velocity (cost of conductor increases as size increases)

Answer 6

• pressure line = 15 ft/s
• return line = 10 ft/s
• suction line = 4 ft/s

Question 7

manifolds

Answer 7

blocks of metal with drilled passages to connect various ports

Question 8

factors in choosing conductors

Answer 8

cost, heat exchange, and compliance

Question 9

causes of hose degradation

Answer 9

• ultraviolet light
• saltwater
• air pollutants
• temperature
• ozone
• electricity

Question 10

types of failures

Answer 10

routine, pinhole, and burst

Question 11

to design a fluid containment system, use STAMP

Answer 11

s = size
t = temperature
a = application
m = media
p = pressure

Question 12

atmospheric pressure

Answer 12

brings fluid into pump and accelerates fluid
