The dew point temperature is at 11.62°C for a relative humidity of 64%

Dew point

The dew point is the temperature the air needs to be cooled to (at constant pressure)

Given that:

Relative humidity (R) = 64%, Dry-bulb temperature(T) = 18 °C.

  • [tex]B=\frac{ln(\frac{R}{100} )+\frac{17.27*T}{237.3+T} }{17.27} =\frac{ln(\frac{64}{100} )+\frac{17.27*18}{237.3+18} }{17.27} =0.0447[/tex]

The dew point (D) is:

[tex]D=\frac{237.3*B}{1-B} =\frac{237.4*0.0467}{1-0.0467} =11.62[/tex]

The dew point temperature is at 11.62°C for a relative humidity of 64%
