Dew You Get The Point? A Pragmatic Understanding of Humidity

2. True or False: If two rooms both have 50% relative humidity, they must contain the exact same amount of water vapor.

3. On a psychrometric chart, dew point is represented by:

4. According to the presentation, what is the "target" indoor summer dew point for a comfortable home designed at 75°F and 50% relative humidity?

5. If a technician measures a 55°F dew point at the return grille but a 59°F dew point at the HVAC unit in a humid attic, what does this most likely indicate?

6. What is the "60-60 Rule" mentioned by Tim De Stasio?

7. True or False: When air leaves an evaporator coil at 100% relative humidity (saturation), it contains less total water than the warmer return air entering the coil.

8. Which phenomenon describes moisture migrating into the OSB roof sheathing at night and being driven back into the attic air by the sun during the day?

9. To stop a surface from sweating (condensating), you must either:

10. True or False: The most humid day of the year (peak dew point) is RARELY the hottest day of the year (peak dry bulb).
