Question: Calculation of gas composition from psychometric data, a stream of moist air has a wet bulb temperature of 80F and a dry-bulb temperature of 130F,

Calculation of gas composition from psychometric data, a stream of moist air has a wet bulb temperature of 80°F and a dry-bulb temperature of 130°F, measured at 800 mm Hg total pressure and high air velocity. Compute the mole fraction of water vapor in the air stream. For simplicity, consider water as a trace component in estimating the film properties.
