How to read a Psychrometric Chart it's easier than you think

What information you need. Any 2 of the 6 air measurements below • dry bulb temperature • moisture content • wet bulb temperature • dew point temperature • enthalpy • relative humidity

What we Know 1. Dry bulb temperature 75 DEG F 2 What we Know 1. Dry bulb temperature 75 DEG F 2. Wet bulb temperature 60 DEG F

Now we look at where the two meet

What we can find out Dewpoint is 50 DEG F Relative humidity 42% Enthalpy 27 btu/lb

To sum it up Dry bulb temperature 75 DEG F Wet bulb temperature 60 DEG F Dewpoint is 50 DEG F Relative humidity 42% (yellow) Enthalpy 27 btu/lb
