Which surface do I measure for pressure? Answered

So this is a fairly simple question, but here it is:  If you have a 5" pipe leading out of a pressurized chamber with a 6" inch disk covering the hole is the amount of pressure pushing the disk down that of 5" or 6".  I am pretty sure it is 5" because it has the equivalent pressure pushing the other way outside of that diameter.  Now if the 5" pipe had a bore of 5" and an outside diameter of 6" would the result be the same?

How would one go about making very small square holes a thin piece of metal?

I'm trying to modify a bracelet that's made out of some very, very thin metal, and I need to make several small square holes all over it. By small, I'm talking 2mm x 2mm small, and they have to be noticeably square shaped. Is there any cleaner way to do this than trying to drill a small hole and using a super small file (if such a thing exists, haha)?

Occasional page layout bug -- giant hole in banner-ad section

I've noticed this happening occasionally for the past few days.  The space where the "banner ad" appears, between the masthead and actual useful content, gets made extra large.  There's still a normal sized banner ad in place, but a lot of blank space below that.  A page refresh usually gets rid of it (and changes the banner ad).

Why a hole in the Ozone?

So I have been looking up a little bit about the ozone layer and have found that about 12% of the ozone layer is reproduced by UV rays every day.  So the whole thing is replaced in about 8.3 days.  Now I think thats a little bit shorter time-span than since we stopped our mass release of refrigerants into the air.  It has even had a bit of time to catch up.  Now if you think about it, less ozone = more UV = more ozone right?  So how On earth did we blow a hole in our ozone layer, it makes absolutely no sense.  Even the fact that some of the halocarbons may still be there makes no sense because it absolutely could not affect the ozone without reacting with it.

How can I hole punch thin plastic page protectors in bulk? Regular punches don't work...?

Update: I found my answer, see comment below.  In short: I used a Carl Heavy Duty hollow-head Hole Puncher, and it works great! I've been using plastic page protectors (these, specifically) in bulk, say about 1000 a month.  However, I need them to be 8.5 x 8.5 and I also need to punch holes that are slightly off from the factory holes.  I'm basically using these as a cheaper alternative to 8x8 scrapbook page protectors (which are prohibitively expensive - say $1 a sheet or so). I've figured out how to quickly cut the pages (using a rotary cutter), and that works great.  However, I am still struggling to find a way to quickly & cleanly punch holes in these things.  The problem is that the plastic binds, stretches, and does not cut cleanly.  I need a very sharp & precise puncher to do this quickly, and I haven't found one yet. I've tried normal 3-hole punchers.  I can punch them one at a time, if I hit the punch hard, and occasionally it binds & sticks (since the plastic stretches instead of breaking and gets caught in the mechanism).  I've tried hand-held punches as well, same result.  Also, aligning each individual page is time consuming as well. The problem with paper hold punchers is that they're made for paper.  They're inaccurate, not sharp, but strong.  The cheap & heavy duty ones alike only differ in how much paper they can punch, but neither are sharp/accurate enough for thin plastic sheets.  Is there a high-quality razor-sharp & ultra-precise hold puncher out there?  I haven't seen any that look even close. I've tried holding them down & drilling them.  The plastic wraps around the drill bit and they rip to shreds. I also tried a leather punch, but the ones I got were much too dull - they just dented the plastic. The only thing that has had some success is a dremel 115 cutter bit.  That actually cuts into the plastic, and if I go carefully (eating a bit at a time) it'll go through a lot of sheets at once.  However, it's messy, takes a lot of setup, and leaves a very messy hole (all chewed up). Ideally, I'd love to line up 10 sheets or so, have a way to align them (a jig?), and then punch them all at once w/o any binding or sticking. Does anyone have any other ideas?  I've thought of melting a hole, but then the pages would all stick together.  I'm completely boggled - how can I do this?  What tool can I buy for this?  What method haven't I tried? Thanks guys!  Any suggestions are appreciated.

Soil for sandy sink hole areas

I would like to put a 3/4" inch hole into a big bottle cap so I can connect a water valve through the cap.  What makes this interesting is that the Cap is very thin metal, and because a valve with a rubber washer is attaching to the cap it needs to be a perfect circle so water wont leak out.  Plus, I would like to be able to mass produce this item (100 an hr), so the method needs to be quick, clean and reliable.

End of World One Step Closer. Or Not.

A vast physics experiment - the Large Hadron Collider (LHC) - reaches a key milestone this weekend ahead of an official start-up on 10 September.Engineers had previously brought a beam of protons - tiny, sub-atomic particles - to the "doorstep" of the LHC.On 9 August, protons will be piped through LHC magnets for the first time.The most powerful physics experiment ever built, the LHC will re-create the conditions present in the Universe just after the Big Bang.This last sentence is the one that's caused a little panic amongst certain groups of the population - they are convinced that the experiment will create miniature black holes which will fall through the LHC towards the centre of the Earth, where they will orbit around, gradually consuing the planet from beneath our feet.When the collider is commissioned, the beams will cross paths at allotted points along the tunnel, smashing into one another with cataclysmic force.My God, have these people never seen Ghostbusters??Scientists hope to see new particles in the debris of these collisions, revealing fundamental new insights into the nature of the cosmos and how it came into being. Now that is seriously cool (well, hot, actually) - to be able to recreate what the whole of reality looked like mere femtoseconds after it started...BBC storyCritics have previously raised concerns that the production of weird hypothetical particles called strangelets in the LHC could trigger the mass conversion of nuclei in ordinary atoms into more strange matter - transforming the Earth into a hot, dead lump.Earlier BBC storyAmusingly paranoid storyAnalog Magazine article

The Large Hadron Collider: is it worth it?

The Large Hadron Collider(LHC) is to be unveiled this year. It is designed to solve the much talked about energy crisis, and hopes to do so, but can it be worth all of it? From Wikipedia- (On October 25, 2005, a technician, José Pereira Lages, was killed in the LHC tunnel when a crane load was accidentally dropped. The construction of LHC was approved in 1995 with a budget of 2.6 billion Swiss francs, with another 210 millionfrancs (€140 M) towards the cost of the experiments. However, cost over-runs, estimated in a major review in 2001 at around 480 million francs (€300 M) for the accelerator, and 50 million francs (€30 M) for the experiments, along with a reduction in CERN's budget, pushed the completion date from 2005 to April 2007.[14] 180 million francs (€120 M) of the cost increase have been due to the superconducting magnets. There were also engineering difficulties encountered while building the underground cavern for the Compact Muon Solenoid. In part this was due to faulty parts lent to CERN by fellow laboratories Argonne National Laboratory or Fermilab (home to the Tevatron, the world's largest particle accelerator until CERN finishes the Large Hadron Collider). [15] The total cost of the project is anticipated to be between US$5 and US$10 billion.[2] On March 27, 2007, there was an incident during a pressure test involving one of the LHC's inner triplet magnet assemblies provided by Fermilab and KEK. No people were injured, but a cryogenic magnet support broke. Fermilab director Pier Oddone stated 'In this case we are dumbfounded that we missed some very simple balance of forces.' This fault had been present in the original design, and remained during four engineering reviews over the following years.[41] Analysis revealed that its design, made as thin as possible for better insulation, was not strong enough to withstand the forces generated during pressure testing. Details are available in a statement from Fermilab, with which CERN is in agreement.[42][43])
