WRT ASD PRACTICE STUDY GUIDE 2026
COMPREHENSIVE SCRIPT QUESTIONS AND
SOLUTIONS
◉ Evaporation. Answer: Process of changing a liquid to a vapor
◉ Dehumidification. Answer: Reducing moisture content in the air
◉ Dry Bulb Temperature. Answer: Temperature degree registered
by a thermometer
◉ Dew Point. Answer: The point at which humidity in the air
reaches saturation or 100 Percent RH
◉ Saturation Point. Answer: Point at which air or materials can
absorb no more moisture, drying stops, and air temperature reached
dew point
◉ Condensation. Answer: Conversion of water from vapor state back
to liquid state
, ◉ Relative Humidity (RH). Answer: The amount of moisture in a
given volume of air, expressed as a percentage, at a given
temperature
◉ Infiltration. Answer: Migration of air into an area from an outside
area due to high VP differential
◉ Balanced Drying. Answer: Ideal drying situation in which the rate
of evaporation is equal to or slightly less than the rate of
dehumidification or ventilation
◉ GPP. Answer: Unit used to measure humidity ratio
◉ 7000 Grains of water vapor. Answer: Equals 1 pound of water
◉ 14 cubic feet of dry air. Answer: Equals 1 pound
◉ Humidity Ratio. Answer: The weight of suspended moisture in air
expressed in GPP
◉ Hygroscopic. Answer: Material that readily absorbs and retains
moisture or water vapor from air in an attempt to reach equilibrium
