Air at 14.7 psia, 50°F (DB), and 60% relative humidity is first heated to 72°F (DB) and then humidified by introducing water vapor (“steam”). The air leaves the humidifying section at 75°F (DB) and 55% Relative Humidity. Plot the process on a Psychrometric
Chart and determine:
The dry-bulb temperature of the steam [°F]
