Heating the window from 70 to 100 F at constant pressure increases the air
volume by (460+100)/(460+70) = 1.057, ie 5.7% no? How many times must we
heat the window to lower the cavity air dew point to 0 F, if it starts at
50% RH and we replace the air that leaves the hole with dry air?
A bunch unless you can somehow figure out which new dry air is different
from the existing on the subsequent heating cycles.
Just go get the window fixed...
