Re: Optimizing Precharged Cylinders
I love it when theory and practice come together. Our team (inspired by 1726's success with a pneumatic trackball launcher, and my traumatic memories of Thermodynamics 350, or whatever the course was) went the empirical route to determine an optimal "precharge" volume. We settled on 15" cylinders precharged to about 5".

Not to say that this was the result of exhaustive research, but we were pleased with the results.

And that's within about 10% of the calculated value. Cool! Why didn't they let me do that on my exams? :-)
