Hi Tom,
I really appreciate your help. I have attached an output example of the type of diagram i am trying to generate.
My problem is that the x-axis is specified as water activity and I cannot seem to change it to fugacity although it should be fugacity since at the given conditions (200C, 1bar) water is in the gas phase.
Basically, my question is what does this water activity in the gas phase mean? is it the same as water fugacity?
The output file reports this data for water but does not say whether its activity or fugacity. Since the plot says activity I assumed this is what is output, although I do not know what this activity means in the gas phase
Thanks again,
David
