[SS-Propellant] Math error: overstated point FYI:

[brodwcjj at integrity.com]

I just fixed a discussion error in the SS2S PDT-5C  Propellant alloy cure rate
page.

I had made a point that a larger volume grain has less surface area per unit of
mass. (True so far ;-)  This was an effort to extrapolate/guesstimate the effect
of grain size on the cooling time prior to curing phase.
But in my hurry, doing the math in my head, I overstated the difference.
The example was a  1 cm cube that has 6cm2 surface area to 1 cm3 volume/(mass)
and a 10cm cube that has 600 cm2 area to 1000cm3 volume/(mass)
The error was I said this is a 100 fold difference in surface area to unit of
(mass)/volume.
Actually it is only a 10 fold difference.   6.0 to 0.6

I'm glad it is not as drastic as I made it out to be  :-)

Thanks  Sjors B. from the Netherlands for catching this oversite,
