Q$11.$ given that the outside air is brought to $24$C without adding any moisture. now to add the moisture you will allow water to evaporate naturally $($adiabetic process$=$constant enthalpy$)$ to bring the RH up to $35\%$ what will the temp of this cooled air in the room? within $1\mathrm{.}5$c

Q$12.$ for question $11$ how many degrees will the temp. drop below $24$C due to the evaporation of liquid water into the air? within $1\mathrm{.}5$C

Q$14.$ some of this $(24$c and $35\%$ RH$)$ now comes in contact with a cool exterior window, whose inside window pane is at $5$C$,$ and the dry air and water vapour mixture coming into contact with this inside pane cools to the temp of the pane. what will the moisture content of the air that gets cooled by this window? within $0\mathrm{.}004$ kg wv$.$kg dry air.

Q$15.$ for rthe situation in question $14,$ how much water vapour condenses out of each kg of dry air that is cooled to the window temp of $5$C$.$ within within $0\mathrm{.}004$ kg wv$.$kg dry air.
