HUMIDITY

The amount of water vapor in the air


Warm air can hold more water than cold air

WARM air can hold MORE water than cold air


This is why

This is why . . .

  • Hot August days feel “muggy.”

  • Your skin dries out in the winter.

  • Phoenix is more comfortable than Orlando

Relative humidity

RELATIVE HUMIDITY

The % of water in the air compared to how much water the air could hold


Psychrometer

PSYCHROMETER

  • Tool used to measure relative humidity


Psychrometer1

Psychrometer

  • Dry bulb

  • Wet bulb

  • The DIFFERENCE between the 2 is used to calculate Relative Humidity


Steps to calculate relative humidity

Steps to calculate Relative Humidity:

  • Measure dry-bulb temperature

  • Measure wet-bulb temperature.

  • Subtract the two to determine the difference.

  • Use a relative humidity table to determine % of water vapor in the air.


Example

Example:

  • Dry = _____

  • Wet = _____

  • Difference = _____
