WRT & ASD EXAM QUESTIONS AND
ANSWERS
Psychrometry: The Explanation Research into how air, humidity, and temperature
interact with one another, as well as the effects these factors have on materials and
comfort levels
The process by which a liquid condenses into a vapor is referred to as evaporation.
The answer is dehumidification. lowering the amount of moisture that is present in
the air
The degree of temperature that is measured by a thermometer is referred to as the
dry bulb temperature.
Dew Point - The ANSWER At the time that the relative humidity in the air reaches
a level of 100 percent, also known as saturation
The point at which air or materials are unable to absorb any more moisture, drying
comes to a halt, and the air temperature reaches the dew point indicating that the
saturation point has been reached.
The ANSWER is condensation. The process of transforming water from its vapor
state to its final liquid state
(RH) stands for relative humidity.) ANSWER The percentage of moisture that is
present in a specific volume of air at a specific temperature can be expressed as the
amount of moisture.
, Infiltration - The Responsive Migration of air into an area from an outside area as a
result of a considerable difference in velocity (VP)
ANSWER: Drying that is Balanced An ideal drying situation is one in which the
rate of evaporation is either equal to or slightly lower than the rate of ventilation or
dehumidification throughout the drying process.
ANSWER The Unit that is used to measure the humidity ratio is the GPP.
7,000 grains of water vapor is equivalent to one pound of water, said the answer.
There is one pound of dry air equal to fourteen cubic feet of air.
The weight of the moisture that is suspended in the air, expressed in grams per day
(GPP), is the humidity ratio.
"Hygroscopic" is the answer. To achieve balance, a material that is capable of
rapidly absorbing and retaining moisture or water vapor from environmental air
The Moisture Content (MC) - The ANSWER The weight or percentage of moisture
in materials, in comparison to the weight of materials that have been dried in an
oven, such as one substance
The ANSWER is permeance. This is a measurement of the flow of water through
materials of a particular thickness.
The different amounts of moisture content that can be found inside a wood material
are referred to as the moisture gradient.
