BTW here is another reference from HyperPhysics which also speaks about RH misconceptions: http://www.youtube.com/watch?v=S7lAlzMBzLQ There is actually a lot of theory in play here. In the time since your response, Joshua and Mark had this exchange about RH. ------------- joshua:The ratio of the partial pressure of the water vapor to the vapor pressure of
water is the relative humidity. mark:The physics definition for RH is: %RH = (Pw/Ps)*100 Where Pw is the partial pressure of the water vapor and Ps is the saturation pressure of water vapor... What's the 'vapor pressure of water'... sound like you're making this shit up. joshua: Nope. "Vapor pressure or equilibrium vapor pressure is the pressure of a vapor in thermodynamic equilibrium with its condensed phases in a closed system. " -------------- In this context we are not dealing with a closed system. Yet there seems to be two kinds of relative humdidity. One which speaks of saturation and one which does not. If saturation pressure pertains to an open system then there are two definitions of RH which aren't equivalent. Harry
