Air at 90 deg F and 30 per cent relative humidity is cooled (isobarically) by an air conditioner to 60 deg F.
a) Is condensation obtained by this cooling?
b) If the answer to part a) is no, then find the final relative humidity. If the answer to part a) is yes, then determine how much condensed water you obtain per 100 lbm of moist air.
c) Repeat parts a) and b) for air at 90 deg F, 60 per cent relative humidity.
