water damage bonus Flashcards
when pre-existing damage is discovered, a restorer should
document it and bring it to attention
rapid drying of structural materials is achieved by
promoting evaporation and dehumidification or ventilation
to minimize safety concerns and to speed structural drying, gypsum board ceilings that are saturated and sagging should be
drained, removed, and disposed
using outdoor air to reduce humidity is an
open drying system
to confirm that proper drying conditions were met, restorers should maintain written logs to include
an atmospheric humidity record and moisture content record
temperature reaching 100% relative humidity is known as
dew point temperature
if dew point changes, what 2 other humidity measurements change with it?
vapor pressure and humidity ratio
if you heat air up but do not add more humidity to it, will the relative humidity increase or decrease?
decrease
if you cool air down but do not change the humidity, will the relative humidity increase or decrease?
increase
vapor pressure, like all other pressure seeks
equilibrium
what safety features does drying equipment need ?
grounded plug
a balanced drying system is achieved when rate of dehumidification is _________ or equal to rate of evaporation
greater
refrigerant dehumidifiers are rated for water removal in
pints per day (ppd)
desiccant dehumidifiers remove moisture from the air through
absorption
