Notes on enthalpy-concentration curves:
( For this part of the project, click here for a sample template.)
    1. Generate the columns as given in the template:
Basis of 1 kg solution,
  x = mass fraction

DH1 = heating of liquid water from 32oF (0oC) to 77oF(25oC)

r = moles of solvent/mole of solute ( for the case of r=infinity, just input it manually)

DHm = heat of mixing (using model obtained before. For the case of r=infinity, just input manually)

DH2 = enthalpy of mixing x kg of solute

Cp,mix = heat capacity (using model obtained before)

DH3,100F = heating mixing from 77oF to 100oF

DH 100F = DH1+ DH2+ DH3,100F (converted to BTU/lb solution)

etc.
2. Plot the three curves (DH 100F vs x, DH 140F vs x, DH 180F vs x) in one graph.
