Hi Don,
With a big southern country boy grin on my face and a big tummy full  
of humility...

I'm a musician with a business degree who began studying piano  
technology at a relatively young age.  I do understand the basics  
that warmer air can hold more moisture and that by heating air the  
relative humidity will go down and vice versa, and that it is more  
complicated than that.  I looked at a web site with formulas for  
calculating dew point, and it looks to be outside the basics for  
business calculus I could actually work for a short time 20 years ago  
and appears to involve calculations for saturation vapor pressure and  
water vapor pressure among other things.  Do you have a simpler  
formula? or do you actually understand all this?
