A small pneumatics spreadsheet

The quantity referenced was not the shaft volume, but the tubing between the solenoid valve and the cylinder.

The two years prior the compressor was on for short bursts at a time. So, both situations are good to have accounted for.

In 2013 Ultimate Ascent, we used air during the main part of autonomous only to trigger our launcher (less than 10 cu in of 60 psi air per cycle); our climb was about 60% pneumatics and 40% electric powered. If we started with full tanks (7 clippards at approx 120psi), in match-duration drills we usually wound up starting the compressor as we lifted the robot half-off the floor. I suspect we used even less air during the matches due to defenses slowing us down.

Did I mention, thank you for tabulating this for us?

Hear, hear!
