Air at 50% relative humidity is cooled isobarically at
1 atm absolute from 90⁰C to 25⁰C.
a) Estimate the dew point and degrees of superheat of the air at
90⁰C.
b) How much water condenses (mol) per cubic meter of feed
gas?
c) Suppose a sample of the 90⁰C air is put in a closed
variable-volume chamber
containing a mirror and the pressure is raised at constant
temperature until a mist forms on the
mirror. At what pressure (atm) would the mist form? (Assume ideal
gas behavior.

Water entering a wet cooling tower at 35°C at a rate of 100 kg/s
is cooled to 22°C in the cooling tower by air that enters the tower
at 1 atm, 20°C, and 60% relative humidity and leaves saturated at
30°C. The makeup water of 22°C is supplied to the outlet to make
the mass flow rate of the cool water the same as that at the inlet,

Atmospheric air at 32°C and 70% relative humidity passes through a cooling section in an air-conditioning duct where the air is cooled below its dew point and some of the water is removed. The air then passes over a heating section where heat is added until the final temperature is 22°C and the relative humidity is 45%. Assume the process occurs at constant pressure of 1 atm. Using the psychrometric chart, determine: (a) The amount of water removed in the...
