The following design conditions apply to the next two problems:

Auditorium was designed to seat $4500$ people. $1\mathrm{.}62$x$10^7$ cubic feet per hour of outside air is used for ventilation.

Design outside temp$=0\backslash$deg F

Use an air density of $0\mathrm{.}08567$lbm$/$cubic feet

Specific heat of air $=\mathrm{.}240$btu$/$lbm$\backslash$deg F

return air temp $=70\backslash$deg F

No recirculation

$1.)$ The temperature at which the air should enter the auditorium is most nearly what? Assume the ventilation air supply temperature offsets the sensible heat gain from the $4500$ people.

$2.)$ Approximately how much heat should be supplied to the ventilation air?
