◉ what are the most effective methods of drying wet wood under
hard surfaces is. Answer: heated air flow
◉ relative humidity is defined as the amount of moisture contained
in the air as compared to. Answer: the maximum amount the air
could hold that temperature
◉ in the restorative drying industry the weight measurement used
to measure water vapor in air is. Answer: grains per pound of air
abbreviated as gpp
◉ what is gpp called. Answer: the humidity ratio
◉ what is the dew point. Answer: the temperature at which air
becomes saturated with moisture Vapor or can hold no more water
vapor
, ◉ when air is cooled its capacity for water is reduced eventually if
temperature is cooled enough the relative humidity will reach.
Answer: 100% or saturation when this occurs the air has reached its
dew point temperature
◉ if surfaces are cooler than the dew point of the surrounding air
water will condense on those surfaces and possibly cause secondary
damage if surfaces are warmer than the dew point of the
surrounding air evaporation can occur. Answer:
◉ what is vapor pressure. Answer: the force exerted by a liquid or
gas on the surrounding environment
◉ the greater the weight of water vapor the greater the water
pressure there for vapor pressure dewpoint and humidity ratio are.
Answer: directly related to each other
◉ is open drying is heaterman appropriate the following options
will keeping building Security in mind are available to the restore.
Answer: ventilation fans open windows air Movers
◉ what is combination drying. Answer: drying systems merge the
benefits of both open and closed drying the use of available dry air
