materials are dry.
16. Hygrometer: measures relative humidity strictly
17. Correct balance of Drying: Important to be familiar w/ equipment performance,
cubic feet of the affected area and the thermo- hygrometer readings
18. Balanced Drying System: Occurs when the rate of evaporation does not exceed the
rate of dehumidification

falls below 70 F.?: Refrigerant
1/6
, 21 Open Drying System: Intentionally using the outdoor air to reduce the indoor

cracks and crevices is known as.?: Infiltration
37. _________ is the ratio of moisture suspended in the air as a percentage of the
total moisture holding capacity of that air: Relative Humidity
38. Humidity Ratio: Directly related to vapor pressure
39. Dew Point: Temperature at which a given volume of air becomes saturated
40. The ''______" on carpet padding is a coating applied to assist the carpet
installer install the carpet: Skin
41. ________ is the moisture that most readily evaporates from wood materials:
