What is most likely happening is that at a pressure of 1atm, your
combination of the dry bulb temperature and the absolute humidity
ratio are on the wrong side of the saturation line. Since that is
physically impossible, the psychometric routine keeps your dry bulb
temperature and resets the absolute humidity ratio to the value it
would be if the relative humidity were 100%.<br>

i'm using a psychrometrics type with dry bulb temperature
and absolute humidity ratio in inputs. Pressure input is
set to 1 atm.<br>
<br>
I have noticed that sometimes there is a difference
between the input humidity ratio and the output humidity
ratio. The difference ratio is about 1 to 12%.<br>
<br>
Could someone explain to me why this difference happens?<br>
<br>
Thank you <br>
