Air at 50% relative humidity is cooled isobarically at 1
Chapter 6, Problem 6.15(choose chapter or problem)
Air at 50% relative humidity is cooled isobarically at 1 atm absolute from 90C to 25e. (a) Estimate the dew point and degrees of superheat of the air at 90e. (b) How much water condenses (mol) per cubic meter of feed gas? (See Example 6.3-2.) (c) Suppose a sample of the 90C 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.)
