Current Attempt in Progress Air at 70.0% relative humidity is cooled isobarically at 1 atm absolute from 75.0C to 15.0C. a. Estimate the dew point and the degrees of superheat of the air at 75.0C. Dew point: i C Degrees of superheat: i C b. How much water condenses (mol) per cubic meter of feed gas? (See Example 6.3-2) mol Suppose a sample of the 75.0C 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.) atm Physical Property Tables
