Let’s model the design studio in spencer lab as a single room with a volume of 10^6 ft3. the air is at normal room temperature and pressure, 72°f, 1 atm, with a humidity ratio (specific humidity) of 0.01 lb of water per lb of dry air.

determine:

a. the relative humidity.

b. the dew point temperature, in °f.

c. the mass of water vapor contained in the room, in lb.
