Hello,
I have built a climatic chamber with +/- 3% (of the relative humidity) and +/- 1 °Cstability. Inside, I cool a slide to the dew point and observe the condensation of water. The higher the relative humidity, the larger the diameter of the condesed water droplet for a normalized duration. This makes sense to me as the vapor pressure of the gaseous water increases for higher relative humidities. Thus, the rate of molecules impinging on the surface (and the rate of condensation) must increase. However, although this sounds trivial, I did not find references that I could cite.
That's why I would like to ask: Do you have any?!
What I found is:
Article Vapor pressures, evaporation, condensation and adsorption
and

Thank you for your help!

Yes. The rate of condensation of water vapour mainly depends on the vapor pressure in the space above the surface of the liquid. It has been established that vapor pressure increases with increase in the concentration of water vapor above the liquid surface.
