ANSWERS) |ALREADY PASSED / 2025 NEWEST VERSION!!
What else can increase evaporation? - ANSWER-If the air has
low Vapor Pressure (VP) and can be heated the added thermal
energy (heat) will also increase the rate of evaporation.
The potential for damage to hygroscopic material is... -
ANSWER-...greatest
when Relative Humidity is
over 70%
Why is it imperative that the RH is lowered below 70% by the
second day? - ANSWER-RH over 70% for more than 48 hours
can provide the right amount of water activity to promote mold
growth.
Hygroscopic materials continue to absorb... - ANSWER-...water
vapor at a given temperature and relative humidity until they
have reached equilibrium.
Moisture levels of ______% will support destructive wood (rot)
decaying fungi to
, grow on wood surfaces. -
ANSWER-20%
When is closed drying used? - ANSWER-When the outside air is
too wet or cold
to aide in the drying
process.
Specifically if the outdoor humidity ration is higher than the
indoor then a closed
drying system is
used.
When using Refrigeration Dehumidification, the temperature of
the affected area must be... - ANSWER-...maintained as close to
80 degrees as possible.
All other things being equal, the temperature that will
increase the rate of
evaporation the most is? - ANSWER-80
degrees
All conventional dehumidifiers and many of the LGRs do not
operate efficiently
