Was that a purely chemical reaction, or was there galvanic activity as well?
I'm not going to sit here and try to tell you there wasn't any stray current running through there. But i can tell you it was an extremely mild solution of deionized water and sulfuric acid. I think the DI water does worse things than the acid. I'm not a chemist, so i can't even begin to explain why. Something about a free ion or ion exchange. It wrecks copper too.
School boat is at my house for the next few weeks.

This is the kind of scenario in which the Engineer in me (college education and whatnot) comes into direct conflict with the Engineer in me (I'm the guy tasked with physically holding this plant together), with often hilarious* results. (* = assuming no one wrote an email to HR.)
The academic engineer says this material should withstand this stress.
The practical engineer notes that boiling, caustic liquid is spraying out of multiple perforations in the material.
Which one is right?
Both, assuming that the proper documentation was filed.
This reminds me of an old joke.
What is the difference between a mechanical engineer and a civil engineer?
The mechanical engineer designs weapons. The civil engineer designs targets.
Today I installed a motion activated switch in the women's bathroom. You know, trying to be environmentally friendly and all. Also the old one got sprayed with too much disinfectant and shorted out.
I set the timer to shut the light off after 8 minutes, i figured five is a little bit too quick. sometimes I poop for more than 5 minutes. It took literally 3 hours for somebody to complain that the lights shut off on them after they were sitting on the throne for over 8 minutes.
That is daily nonsense. I've got 3 contractors working on 2 different multi thousand dollar jobs. I'm in the process of writing 3 different CERs for different future projects. I've got 8 applications for 2 open positions I have. I still don't have a damn quote for a scissor lift. Oh and somehow I still manage to keep the line going. I am not an engineer. When the pipe busts, we just replace it. But this time was special. See I built a shield.
The root cause of the pipe failure is actually because of a genius design I came up with years ago. See we have this tank called the etch tank and it contains sodium hydroxide and a blend of herbs and spices. Long story short when it inevitably overflows out of the tank (or general carryover) it turns into concrete. If it gets between the tanks It can actually push the walls of the tanks together cracking and breaking the tank or moving the tank. So we take the rinse water from our anodized bath which is sulfuric acid and pump it between the tanks spraying down the caustic solution with acid solution to help dissolve all that sodium hydroxide concrete. The downside is that acid rinse water will almost destroy everything and anything else in it's path.
