can any one tell me the
Global K value Model
and
Global Enthalpy Model??

I built the model in ChemCAD however the results seems not the same as what I have read from book "Absorption Chillers and Heat Pumps" by Keith

In that book there is one example said that
Pressure 0.673 kPa
Temperature 32.7 degree C
and LiBr X(i) percentage 56.7

I chose Latent heat model and NRTL K value Model but when I typed in 32.7 C and 0.567 mass percentage the pressure is higher than 1 kPa
Thank you very much
