Select the parameter (dew point, temperature, or relative humidity) and enter the required parameters. The tool will immediately calculate its value.
“a selected temperature at which the vapours of water begin condensing is known as the dew factor”
one can find the humidity elements in many theoretical calculation formulas, charts, dew factor calculator, and several other ways. Let's address a couple of instances here to better clarify your idea.
Example
How to calculate the dew point when the temperature and relative humidity of the environment are 28°C and 65%?
Solution:
Here we have:
Ts = (b α(T, RH)) / (a - α(T, RH))
As we know that:
a = 17.62 and b = 243.12
α(T, RH) = ln(RH/100) + aT / (b + T)
Substitute the given values:
α(T, RH) = ln(65/100) + 17.62*28 / (243.12 + 28)
α(T, RH) = ln(0.65) + 493.36 / 271.12
α(T, RH) = -0.4307 + 1.8196
α(T, RH) = 1.3889
Performing dew point temperature calculations:
Ts = (243.12 * 1.3889) / (17.62 - 1.3889)
Ts = (337.475) / (16.2311)
Ts = 20.8°C
So, the dew point is approximately **20.8°C**. You can cross-verify this result using a dew point calculator for precise results.
If the dew factor rises sufficient upto 70, it way that you may experience a big growth on your frame weight and the sensation of the temperature will increase significantly.
typically, the dew factors of 50s or lower than this are taken into consideration appropriate while the summer season days are occurring. If it increases up to 60 or 65, it feels more humid than natural.
