Q: When is a drying job done?
Answer:
A moisture meeter indicates we have met our dry goal
Q: The moisture sensor can be used to verify our drying goal has been met (True or False)
Answer:
False
Q: Moisture sensors and IR cameras are effective tools for:
Answer:
quickly locating moisture in carpet and pad and establishing a wet perimeter.
Q: What does a thermo-hygrometer measure?
Answer:
Temperature and relative humidity
Q: When do (IR) infrared cameras indicate possible moisture in materials?
Answer:
Materials surface temperature cools as water evaporates. Moisture in materials can cause
temperature variations due to differences in thermal conductivity.
Q: once an area is identified with an infrared camera as a suspect of being wet, that area must
be verified with:
Answer:
A moisture meter or sensor
Q: Psychrometric conditions have a direct effect on the rate at which moisture moves within
materials, as well as from wet materials. (True or false)
Answer:
True
Q: What are the three things restorers can manipulate to promote drying? (sometimes called the
drying pie)
Answer:
Humidity, Airflow, and Temperature
Q: The ratio of moisture in the air, as compared to the maximum amount the air could hold at
that temperature is…
Answer:
Relative Humidity (RH)
Q: What is the ratio of the weight of water vapor mixed with a specific weight of dry air called?
Answer:
Humidity Ratio
Q: The __ difference between the dew point temperature of surrounding air and the
temperature of the affected material (if warmer), the greater the potential for drying (smaller or
greater)
Answer:
greater
Q: To promote effective drying restorers need to control:
Answer:
surface temperature of the wet materials, air temperature of the drying chamber, and vapor
pressure of the drying chamber
Q: Lowering the temperature in a drying chamber my cause:
Answer:
Condensation
Q: If you increase the temperature in a drying chamber, relative humidity will…
Answer:
Decrease
Q: Evaporation will increase when
Answer:
wet materials are made warmer, when drier air is used, and when air is moved across the wet
surface.
