Re: Anyone have a R/H or Dew point charts in Excel? I ended up starting back over from scratch. The original had macros in it and it worked fine, but it was a bit overwhelming for my painter, and I wasn't sure if it would run well on other machines, so I made a new workbook that uses all worksheet functions instead of macros.
Dew Point: The temperature at which moisture will condense on the surface. No coatings should be applied unless the surface temperature is a minimum of 5°F above this point. Temperature must be maintained during curing. Example: If air temperature is 70°F and relative humidity is 65%, the dew point is 57°F. No Humidity Formulas If you want to do your own calculations or program a computer, this page contains various formulas used for calculating relative humidity, dewpoint temperature, and other quantities such as air density, absolute humidity, and the height of cumulus cloud bases, which are related to the moisture content of air.
Calculate the dew point in celsius with this Dew Point Calculator. This calculator uses the Magnus formula to calculate the dew point when the temperature range is between -45 and 60 degrees celsius. Assuming no changes in air pressure.
The dew point is the temperature to which air must be cooled to become saturated with water vapor. When further cooled, the airborne water vapour will condense to form liquid water . When air cools to its dew point through contact with a surface that is colder than the air, water will condense on the surface.
