The psychrometric chart is used to analyse the properties of air. I remember years ago my teacher mentioned that with two properties you could find the others. But, he also mentioned that two of the properties would yield no answer... What are they, I forgot.

I am talking about the psychrometric chart use to analyse dry bulb, wet bulb, relative humidity dew point specific volume, specic humidity ect... in heating ventilation and air conditioning

I think he may have meant wet bulb & enthalpy. Using a paper chart, they're so close, the lines are nearly parallel. Knowing enthalpy & wet bulb wouldn't give an accurate answer. Of course, with these high-falutin computer programs, it's not a problem.

Psychometrics is the measurement of people's character by asking hundreds of similar questions and telling them things like how honest they are and whether they are people or task oriented.
No answer or no change? Do words like isobaric and isothermal ring any bells?
Perhaps you could explain what you were being taught at the time?
