Is it possible to use an Excel add-in from Rapid Q (that is, without using Excel itself) ?
I found a (free!) add-in for Excel to calculate steam and water energy (and things, like boilingpoint) but need to do such calculations in a program. The formulas can be found at http://www.cheresources.com/iapwsif971.pdf but I don't have a clue as to how to implement them. So as the add-in has the functions I would love to be able to use them ?
