Relative Humidity facts
While investigating facts about Relative Humidity Calculator and Relative Humidity Formula, I found out little known, but curios details like:
Rollie pollies (pill bugs) are not insects, they are crustaceans. They are related to shrimp and crayfish, breathe with gills, and need humidity or moisture to survive.
how relative humidity is measured?
The original camera negatives of Gone With the Wind, Ben Hur, and other documents and memorabilia, are stored in an underground salt mine, as the constant temperature and relative humidity offers natural protection
What relative humidity does mold grow at?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what relative humidity is comfortable. Here are 14 of the best facts about Relative Humidity Chart and Relative Humidity Calculator Chart I managed to collect.
what relative humidity should my house be at?
-
When humidity is measured as the amount of water vapor in a specific unit volume of air it is referred to as absolute humidity. When it is measured as moisture in the atmosphere to moisture the atmosphere can hold it is referred to as relative humidity.
-
The wet and dry bulb psychrometer works by evaporating water on a wet bulb which causes the bulb's temperature to drop. It shows a lower temperature than the dry bulb. The difference is calculated and used to determine relative humidity.
-
Hygrometers measure RH (relative humidity). It can take as long as two hours to get an accurate reading from a hygrometer. Results are not instant like with thermometers.
-
Exhaled breath is so saturated by moisture in your lungs that it has a relative humidity of 100%
-
In 1783 Horace Benedict de Saussure invented a hygrometer using a human hair to determine relative humidity.
-
The city of Needles, CA (One of the driest localities on earth) holds two rain-related world records: the hottest rain to ever occur (115F/47C) and the lowest humidity at which rain has ever occured, at 11%.
-
A hygrometer can also be referred to as a "humidity sensor" or a "relative humidity indicator".
-
Weather stations usually have a hygrometer for measuring the relative humidity in the atmosphere.
-
Cacao plants can only grow within a narrow strip of land roughly 20 degrees north and south of the equator where temperature, rain, and humidity all stay relatively constant throughout the year. They are under threat of extinction by 2050 due to warmer temperatures and dryer weather conditions
-
Weather reporters report on relative humidity as this can help warn people about potential health risks in high humidity conditions.
Relative Humidity data charts
For your convenience take a look at Relative Humidity figures with stats and charts presented as graphic.
Why relative humidity increases when air is cooled?
You can easily fact check why relative humidity is important by examining the linked well-known sources.
A of a device called a Hair Hygrometer which uses actual human hair to record relative humidity fluctuations in the air
Mold spores are 3 to 40 microns in size.While controlling the humidity of a home may be a bit more of a challenge due to the cost of a dehumidifier, capturing mold spores with an air purifier is a relatively simple task. - source
