On the other hand, if the relative humidity is high, the water
on the wet-bulb will evaporate slowly and the wet-bulb temperature
will not change much.
You will be using a relative humidity chart to record the percentage of the relative humidity. When the relative humidity is high there is a greater chance for precipitation. When the relative humidity is low there is a lower chance for precipitation. |
Directions
on how to use the Relative Humidity chart:
When given wet and
dry bulb readings.
Dry bulb= 28 degrees
Wet bulb = 14 degrees
1. Subtract the wet
bulb reading from the dry bulb reading. 28 - 14 = 14 (difference)
2. Use the chart by
locating the dry bulb reading (28)on the left hand side of
the chart and lining that up with tthe difference (14) on the
top of the chart. Therfore the relative humidity is 17%. Little
chance of precipitation.
When the relative
humidity reaches 100% then it will rain, snow, sleet or hail.

Good explanation about relative humidity. This is why we use
ReplyDeletedehumidifiers. If there is too much moisture inside home, a dehumidifier can be utilized to help us remove the excess moisture and get relative humidity back at an ideal level.
