Newest Actual Questions & Answers (A+ Guide Solution)
The most critical course of action in restoration during is to _______ an begin
__________ as soon as possible - respond quickly & mitigation
if surfaces are _____ then the dew point of the surrounding air, water will
condense on those surfaces and possibly cause secondary damage. if surfaces are
_____ then the dew point of the surrounding air, evaporation can occur. - cooler
warmer
______is the force exerted by a gas (vapor molecules) on the surrounding
environment. - vapor pressure
vapor pressure, dew point, and humidity ratio (GPP) are directly related to each
other. when one increases the other two _____. when one decreases the other
two ______. - increase
decrease
water vapor pressure is the force that drives higher convention of humidity from
one space to another in an attempt to seek ____ with lower concentration of
water vapor. - equilibrium
the ability for water vapor to diffuse through a solid material is expressed as the
materials _____ - permeance
drying systems (provide name and brief descriptions of each) - open: intentional
using outdoor air
closed: using mechanical dehumidification only
combination: using outdoor air combo with mechanical dehumidification
open , closed or combination - how to decide? - is the outside air humidity ratio
lower?
, no : use closed drying
yes: is the outside air warmer than 70 F?
no: may use combination drying
yes: is the security, weather, customer preference
agreeable to open drying?
no: use closed drying
yes: can use open drying
if open drying is determined appropriate, the following options (while keeping
building security in mind) are available to the restorer - - using ventilation
- open windows
-install fans to create pressure differentials & air exchange
____ drying systems merge the benefit of both open and closed drying: the use of
available dry air from outside and the control offered by a closed system and
mechanical dehumidification - combination
Elevating the temperature of a material will increase the _____ ________
associated with the moisture in the material. - vapor pressure
if the surface temperature of the material is higher than the _____ temperature
of the surrounding air , evaporation may occur. - dew point
which of these surfaces temperature would have the fastest rate of evaporation?
10 degree below dew point
20 degree above dew point
30 degree above dew point - 30
class 1 water intrusions involve the ____ amount of water absorption, with less
than __ % of the area surface being wet porous materials. - least , 5%
class 2 water intrusions involve a _____ amount of water absorption, with more
than ___ but less than ___ of are surface being wet porous materials - significant
5%-40%
