Dew Point Calculation in a Gas Mixture

Hi Abby.

Surely the water vapour will assume its own vapour pressure. The higher its vapour pressure then just the less of the other gases?

Surely the water vapour pressure is constant, regardless of the rising total pressure on account of the pressure of each additional gas?

With or without air is the water vapour dew point not the same? This is why wet air is lighter than dry air - """""WHAT"""""waters atomic mass is less?

yes grump a molecule of water vapour has less mass than a molecule of O2 or N2

H = 1 N = 14 O = 16

O2 = 32, H20 = 18

I checked in the ASHRAE 20005 HOF, chapter 18 they got figure 2 for dewpoint of water vapour in flue gas. Looks like the Dalton appraoch to me, I pulled it corectly out of my ass

figure 3 is for the dewpoint of the acids it loos like
