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 from outside and control
offered by a closed system and mechanical dehumidification
elevating the temperature of a material will - ANSWER ✓ increase the vapor
pressure associated with the moisture in the material
if the surface temperature of the material is higher than the dew point temperature
of the surrounding air - ANSWER ✓ evaporation may occur
equilibrium - ANSWER ✓ water vapor pressure is the force that drives higher
concentrations of humidity from one space to another in an attempt to seek
equilibrium with a lower concentrations of water vapor
the ability for water vapor to diffuse through a solid material is expressed as the
materials - ANSWER ✓ permeance
drying systems - ANSWER ✓ open closed and combo
plywood - ANSWER ✓ represents the was wood material with the least
engineering and that's the most natural fiber bonding it is resistant to swelling and
denomination due to its wood veneer assemblies which are glued under extreme
pressure
wet particle board would normally be - ANSWER ✓ removed and replaced
Plasticity plastic laminate flooring is made of - ANSWER ✓ MDF and has a resin
saturated appearance layer normally removed in water restoration due to its
construction and installation components
