Nomograph application
I regularly need to use a nomograph for distillations. Now there is this great app from Sigma-Aldrich http://www.sigmaaldrich.com/Area_of_Interest/Research_Essent...
Does anybody know of a way to make a locally executable flash app out of it?

I downloaded the Flash object, and it (seems to) work(s) off-line if you open it in a Flash-enabled browser.
(edit: Oops, it seems to have conked when run off-line; the movable line has veered off chart C!)

I wanted to apply this in the following way. My compound is reported to boil at 190/2mm. What would be the predicted bp at 6mm? I couldn't move the
sliders in a way that would get the answer.

I was able to do this and get 212.4 C. (Approximate, I couldn't hit 6 mm or 190 mm exactly, but I was close.)
You can do this by adjusting what the pivot is. My first step was to get 2 mm on 'C' and 190 C on 'A' (189.9 C actually), then I made slider B the
pivot, then adjusted slider A so that the point on curve C came to 6 mm (5.889 mm actually), and this gave me 212.4 C on graph A.
(Meanwhile, BP at 760 mm = 382.6 C)

The exact answer is 212.7 degrees centrigrade. Assuming we were talking about centigrades in the first place. Just enter the known variables and hit
set. This will lock them into place.
Great app, thanks for posting. Also notice the bars on the right side with more info.

Since it's relevant theres a rotovap simulator here thats predicts the degreee of separation of any solvent mix you enter in. Its an estimate but i
find it useful.
