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? http://www.natmus.dk/cons/tp/atmcalc/atmoclc1.htm Tanner
