Hi All,

I'm trying to calculate the latent heat of vaporization of a chemical using the equation found in Perry's Chemical Handbook, Table 2-150. It gives the latent heat equation and chemical specific constants. My issue is I can't get that equation, which outputs J/kmol, to convert correctly to BTU/lb. I tried using water as a test chemical to make sure I was using the equation correctly, and it won't work.

The table says the listed are "latent heat values at Tmin X 1E-07". For water, this comes out to (and is listed as)4.4733x10^-7 J/kmol at 0C.


Does anyone have experience with using this equation from Perry's or converting it to BTU/lb?



Thanks!
