Re: Calculations related to pneumatic cannon.

The ideal gas law is probably more relevant to this, as it considers changes in pressure, volume, and temperature, all of which happen. You'll probably have to do it the same way I'm looking at when I someday get to more complicated projects--you measure your velocity, calculate your pressures and v...
