As to the PCV. Pressure is pressure. But PVC (the kind they use in for pipe) is brittle. Liquids don't throw shrapnel the same way air does when the pipe shatters. The density of air is so small & the distances involved are small so you do not get significant pressure spikes from "water hammer"
The PVC is not going to randomly burst under normal conditions. But if it does, maybe it gets bumped in the wrong way, something hits it, etc, it has a bad failure mode. Well documented. Big legal liability. Especially for any mentors on the team that are registered professional engineers. Makes the cost for other material seem small. |
I see the liability. Thankfully or should I say unthankfully none of our mentors are enginners. Our lead mentor teaches tech our second lead is a programming and math teacher and our third mentor is the orchestra teacher. But... yea I see what your are saying our bot exploding in the middle of a crowded place isnt good for anyone and is especially bad if its at a real arena like madison square garden (im pretty sure we cant afford to fix that) I see the point and my final decision is no to pvc. However I will be on the lookout for tubing.
