What is the value of humidity ratio for 313K DBT & 80%? Because in psychrometric chart, 313K DBT line and 80% RH doesn’t intersect. Could anyone help me regarding this? Thank you.

Please explain “adabiatic”….a term i keep running into using psych programs/apps

I agree with Don Gatley that absolute humidity can be confusing if you are trying to use one of the many past formal definitions. I only use it as a generic term for any humidity measurement that solely depends on the water vapor content and not the drybulb temperature of the air. Thus, RH, wetbulb temperature, degree of saturation, and some other terms are not “absolute” humidity measures, but humidity ratio, vapor pressure, dewpoint temperature and several other humidity measurements are “absolute”.

Thanks for the physics refresher, Allison! Question, in real world applications, when do we have to worry about psychrometrics on the interior volume of a home that is well ventilated? What problems may we expect?
