// In the given figure 6.8 in the book, drawing the tangent to the 200F curve at 60 wt% H2SO4, we find that it intersects the 0%(pure water) axis at 25 Btu/lbm, and the 100% H2SO4 axis at -100Btu/lbm. i.e.
h_water_per_pound = 25;//[Btu/lbm]

// also molecular weight of water and sulphuric acid are

M_sulph = 98;//[lbm/lbmol]
// Using equation 6.20 given in the book we have
h_water = h_water_per_pound*M_water;//[Btu/lbmol]
h_sulph = h_sulph_per_pound*M_sulph;//[Btu/lbmol]
