psychrometric chart question
(OP)
Hi all ,
Knowing that wetbulb temperature and enthalpy lines are not identical (only approximated on chart) .
I have a point of known wetness (kg/kg) and known dry bulb temperature and I want to know it's exact enthalpy . Then indentify the point that has the same enthalpy with an RH% of 100% .
How can I do that on a psychrometric chart ?
Thanks in advance

You have enthalpy values on the bottom/right side as well as above the saturation curve (diagonal) on your chart.
Place your pencil on your point and adjust straight edge until you read the same enthalpy on both 'sides of the chart. One side being the right/bottom and the other being the diagonal above the saturation curve.
Better answer is to use one of the free p-chart calculators online. I use one at http://sugartech.co.za/psychro/
