Hi Guys,
Can one of you clever guys tell me how to work out how much moisture is lost when air travels over a coil. If for example air on is 32°C and 85% RH, and the coil temperature is +5°C, what would the RH be of the air leaving the coil if it was, say 12°C?
Can someone explain how to read this from a psychrometric chart please?

Thanks
