Leak detection

Post by ed »

I have these funny cylinders that are water tight. I'd like to submerge them in my pool for some period and then check them for leaks.

Question: is there some easy to find and readily available chemical/substance/foodstuff that would react with water that might leak in and thus provide an objective indication of said leak?

Drain maintenance guys use stuff like this. Might help.

Shit happens. The older you get, the more often shit happens. So you have to try not to give a shit even when you do. Because, if you give too many shits, you've created your own shit creek and there's no way out other than swimming through the shit. Oh, and fuck.

Or, silica gel is inexpensive. It'll swell if there's any water getting into your cylinders.

I sunk the damn thing in the pool. I'll pull it out tomorrow and report back. If it leaks at all it will leak a lot is my thought.

It is down about 7 feet. ~17 psi right?

I think it's about one atmosphere (15 psi) for every ten metres (34 feet) so seven feet down is only about three psi.

:x :x

Yes but you need to add the pressure ABOVE the waters surface = 14psi so the total is 14+3=17


Oui?

Bought 500 tear gas rounds that were in these things. Sold the tear gas sans cases. Thought I'd package some survival stuff in them. Too lazy so I'll just verify their water tightness and move them out.

eta This isn't really that interesting but given that you all seem to have calcified social lives I thought that it might actually be interesting compared to what you are used to.

"Pressure testing surplus plastic cylinders and then arguing about the pressure computation."

We are pathetic. :P

I'll post pictures tomorrow. Perhaps I'll use Lake Ed as the backdrop (if your hearts can stand it)

Well yes, but that only matters if you sucked a perfect vacuum in the cylinders before placing them in the pool. If you started out with the cylinders full of regular ground-level air, as I guess you did, then the pressure difference, 3 psi, is what matters.

If someone slashes the tires on your truck leaving them totally flat, then you wouldn't say they were still inflated to a pressure of 15 psi.

Naturally. :x

Seriously ... What in the name of feet and yards does the outside know what is going on in the inside? And what about atmospheric pressure? Is water magical in some way so that it suddenly negates the atmosphere? I mean that 14psi holds me together. Are you saying (as I think you are) that if I go 1/10" under the surface that the pressure on me is ~0psi? If so, why then do divers not explode upon entry?

Here is a very core question: do you know what you are talking about or not? I do not so if you do I will defer but if you, like me, are ignorant then we can continue arguing like two drunks on a street corner at 3am.

Re: Leak detection

Post by ceptimus »

The point is that you are talking about leak testing a cylinder by putting it underwater. When you leak test something, it's the pressure difference, inside to outside that matters.

Let's conduct the following thought experiment - you start with the cylinder full of air at normal atmospheric pressure, but you've drilled a hole in the cylinder wall and attached a hose to it - we'll assume that the hose and the hose attachment are perfectly watertight, so any leaks discovered won't be due to the hose attachment but would have been present all along.

Now you submerge the cylinder seven feet down in your pool, but the hose reaches up to the surface like a snorkel so the open end is still open to the air.

The pressure just due to the water is about 3psi. Let's imagine that there is a tiny pinprick leak in the cylinder that allows one cubic inch of water to leak in every hour under those conditions.

Now you attach the end of the hose to your vacuum pump and pull a pretty good vacuum into the cylinder. We have to assume that both the hose and the cylinder are strong enough to withstand this without being sucked flat.

Now normal atmospheric pressure is about 14.7 psi, and let's say your vacuum pump pulls the pressure down to just 0.7 psi. Now the pressure acting on the cylinder is 14+3 = 17 psi. Assuming that the pinprick leak isn't sealed up by the compression of the cylinder walls and remains the same size as it was before, we'd now expect the water to leak in faster than before - with a roughly linear relationship between pressure and flow you'd now expect

1 x (17/3) cubic inches of water to enter every hour - so nearly six times as fast as before.

If you didn't want to use a vacuum pump and had a deep enough pool, you could get the same pressure difference (14 psi extra) by taking the cylinder down an extra 32.2 feet.

All you need to know is that the column of air, one square inch in cross section and extending up from the ground right up to space weighs the same as a column of water one square inch in cross section and 33.8 feet high: the sixty-mile high column of air and the 33.8 feet high column of water both weigh 14.7 pounds. Of course the air gets thinner and lighter the higher you go and the column is very slightly tapered due to the curvature of the Earth - but that makes no difference - it still weighs the same as the 33.8-foot high column of water.

(Actually the taper is negligible when you consider that space is generally agreed to begin about sixty miles up, and the Earth's radius is about four thousand miles. Likewise the reduction in gravity over a height of sixty miles is also negligible.)

To put it another way, and answer your 'explode' question, it's true that if you could submerge the cylinder seven feet down while it's full of air and then magically remove all the Earth's atmosphere (we'll assume for now that the pool wouldn't boil away as a result) then the pressure inside the cylinder would indeed be higher than the water outside by 14.7 - 3 = 11.7 psi so any leaks would then be revealed by air bubbling out of the cylinder through the cracks/holes rather than water leaking in.

OK. 24+ hours under enormous pressure in my tac deductible, open air pressure cavatron.

No water inside.

Rigorous testing complete. Marketing to commence momentarily.

My associate Prof. Rajnesh J. Suorapani of the Punjabi Institute of Atmospheric Studies evalueted my experimental approcah, implimentation and results and reported this:
ਗੱਲ ਇਹ ਹੈ ਕਿ ਤੁਸੀਂ ਇੱਕ ਸਿਲੰਡਰ ਨੂੰ ਪਾਣੀ ਦੇ ਅੰਦਰ ਪਾ ਕੇ ਲੀਕ ਕਰਨ ਦੀ ਗੱਲ ਕਰ ਰਹੇ ਹੋ. ਜਦੋਂ ਤੁਸੀਂ ਕਿਸੇ ਚੀਜ਼ ਨੂੰ ਲੀਕ ਕਰਦੇ ਹੋ, ਤਾਂ ਇਹ ਦਬਾਅ ਦਾ ਅੰਤਰ ਹੁੰਦਾ ਹੈ, ਅੰਦਰੋਂ ਬਾਹਰ ਜੋ ਇਸ ਲਈ ਮਹੱਤਵਪੂਰਣ ਹੈ.

ਆਓ ਹੇਠ ਦਿੱਤੇ ਵਿਚਾਰ ਪ੍ਰਯੋਗ ਦਾ ਆਯੋਜਨ ਕਰੀਏ - ਤੁਸੀਂ ਸਧਾਰਣ ਵਾਯੂਮੰਡਲ ਦੇ ਦਬਾਅ ਤੇ ਹਵਾ ਨਾਲ ਭਰੇ ਸਿਲੰਡਰ ਨਾਲ ਸ਼ੁਰੂਆਤ ਕਰਦੇ ਹੋ, ਪਰ ਤੁਸੀਂ ਸਿਲੰਡਰ ਦੀ ਕੰਧ ਵਿੱਚ ਇੱਕ ਮੋਰੀ ਡ੍ਰਿਲ ਕੀਤੀ ਹੈ ਅਤੇ ਇਸ ਨਾਲ ਇੱਕ ਹੋਜ਼ ਲਗਾ ਦਿੱਤੀ ਹੈ - ਅਸੀਂ ਮੰਨ ਲਵਾਂਗੇ ਕਿ ਹੋਜ਼ ਅਤੇ ਹੋਜ਼ ਦੀ ਲਗਾਵ ਹੈ. ਬਿਲਕੁਲ ਵਾਟਰਟਾਈਟ, ਇਸ ਲਈ ਲੱਭਿਆ ਕੋਈ ਵੀ ਲੀਕ ਹੋਜ਼ ਦੀ ਕੁਰਕੀ ਕਾਰਨ ਨਹੀਂ ਹੋਏਗਾ, ਪਰ ਸਾਰੇ ਮੌਜੂਦ ਹੋਣਗੇ.

ਹੁਣ ਤੁਸੀਂ ਸਿਲੰਡਰ ਨੂੰ ਆਪਣੇ ਪੂਲ ਵਿਚ ਸੱਤ ਫੁੱਟ ਹੇਠਾਂ ਡੁਬੋਉਂਦੇ ਹੋ, ਪਰ ਹੋਜ਼ ਇਕ ਸਨੋਰਕਲ ਦੀ ਤਰ੍ਹਾਂ ਸਤਹ ਤਕ ਪਹੁੰਚ ਜਾਂਦੀ ਹੈ ਤਾਂ ਕਿ ਖੁੱਲ੍ਹਾ ਸਿਰਾ ਹਾਲੇ ਵੀ ਹਵਾ ਲਈ ਖੁੱਲ੍ਹਾ ਹੈ.

ਪਾਣੀ ਦੇ ਕਾਰਨ ਦਬਾਅ ਲਗਭਗ 3psi ਹੈ. ਆਓ ਕਲਪਨਾ ਕਰੀਏ ਕਿ ਸਿਲੰਡਰ ਵਿਚ ਇਕ ਛੋਟਾ ਜਿਹਾ ਪਿੰਨਪ੍ਰਿਕ ਲੀਕ ਹੈ ਜੋ ਉਨ੍ਹਾਂ ਹਾਲਤਾਂ ਵਿਚ ਇਕ ਘੰਟਾ ਇੰਚ ਪਾਣੀ ਹਰ ਘੰਟੇ ਵਿਚ ਲੀਕ ਹੋਣ ਦਿੰਦਾ ਹੈ.

ਹੁਣ ਤੁਸੀਂ ਹੋਜ਼ ਦੇ ਅੰਤ ਨੂੰ ਆਪਣੇ ਵੈਕਿumਮ ਪੰਪ ਨਾਲ ਜੋੜਦੇ ਹੋ ਅਤੇ ਇਕ ਵਧੀਆ ਖਲਾਅ ਨੂੰ ਸਿਲੰਡਰ ਵਿਚ ਖਿੱਚੋ. ਸਾਨੂੰ ਇਹ ਮੰਨਣਾ ਪਏਗਾ ਕਿ ਹੋਜ਼ ਅਤੇ ਸਿਲੰਡਰ ਦੋਵੇਂ ਸਖਤ ਚੂਸਨ ਤੋਂ ਬਿਨਾਂ ਇਸ ਦਾ ਮੁਕਾਬਲਾ ਕਰਨ ਲਈ ਕਾਫ਼ੀ ਮਜ਼ਬੂਤ ​​ਹਨ.

ਹੁਣ ਆਮ ਵਾਯੂਮੰਡਲ ਦਾ ਦਬਾਅ ਲਗਭਗ 14.7 ਪੀਐਸਈ ਹੈ, ਅਤੇ ਮੰਨ ਲਓ ਕਿ ਤੁਹਾਡਾ ਵੈਕਿumਮ ਪੰਪ ਦਬਾਅ ਨੂੰ ਸਿਰਫ 0.7 ਪੀਐਸ ਤੱਕ ਖਿੱਚਦਾ ਹੈ. ਹੁਣ ਸਿਲੰਡਰ 'ਤੇ ਕੰਮ ਕਰਨ ਵਾਲਾ ਦਬਾਅ 14 + 3 = 17 ਪੀ ਐਸ ਹੈ. ਇਹ ਮੰਨਦੇ ਹੋਏ ਕਿ ਪਿੰਨਪ੍ਰਿਕ ਲੀਕ ਸਿਲੰਡਰ ਦੀਆਂ ਕੰਧਾਂ ਦੇ ਕੰਪਰੈੱਸਸ਼ਨ ਦੁਆਰਾ ਮੋਹਰ ਨਹੀਂ ਲਗਾਈ ਗਈ ਹੈ ਅਤੇ ਪਹਿਲਾਂ ਜਿੰਨੀ ਆਕਾਰ ਵਿਚ ਰਹਿੰਦੀ ਹੈ, ਹੁਣ ਅਸੀਂ ਉਮੀਦ ਕਰਾਂਗੇ ਕਿ ਪਾਣੀ ਪਹਿਲਾਂ ਨਾਲੋਂ ਕਿਤੇ ਤੇਜ਼ੀ ਵਿਚ ਲੀਕ ਹੋ ਜਾਵੇਗਾ - ਦਬਾਅ ਅਤੇ ਪ੍ਰਵਾਹ ਦੇ ਵਿਚਕਾਰ ਲਗਭਗ ਇਕ ਲੰਬੇ ਰਿਸ਼ਤੇ ਦੇ ਨਾਲ. ਤੁਸੀਂ ਹੁਣ ਉਮੀਦ ਕਰਦੇ

ਹਰ ਘੰਟੇ ਵਿਚ ਦਾਖਲ ਹੋਣ ਲਈ 1 x (17/3) ਕਿicਬਿਕ ਇੰਚ ਪਾਣੀ - ਇਸ ਤਰ੍ਹਾਂ ਪਹਿਲਾਂ ਨਾਲੋਂ ਛੇ ਗੁਣਾ ਤੇਜ਼.

ਜੇ ਤੁਸੀਂ ਵੈੱਕਯੁਮ ਪੰਪ ਦੀ ਵਰਤੋਂ ਨਹੀਂ ਕਰਨਾ ਚਾਹੁੰਦੇ ਹੋ ਅਤੇ ਇਕ ਡੂੰਘਾ ਪੂਲ ਹੈ, ਤਾਂ ਤੁਸੀਂ ਸਿਲੰਡਰ ਨੂੰ 32.2 ਫੁੱਟ ਥੱਲੇ ਲੈ ਕੇ ਉਹੀ ਦਬਾਅ ਅੰਤਰ (14 ਪੀਐਸਈ ਵਾਧੂ) ਪ੍ਰਾਪਤ ਕਰ ਸਕਦੇ ਹੋ.

ਤੁਹਾਨੂੰ ਬੱਸ ਇਹ ਜਾਣਨ ਦੀ ਜ਼ਰੂਰਤ ਹੈ ਕਿ ਹਵਾ ਦਾ ਕਾਲਮ, ਕਰਾਸ ਸੈਕਸ਼ਨ ਵਿਚ ਇਕ ਵਰਗ ਇੰਚ ਅਤੇ ਜ਼ਮੀਨ ਤੋਂ ਸੱਜੇ ਪਾਸੇ ਤੱਕ ਦਾ ਹਿੱਸਾ ਇਕ ਕ੍ਰਾਸ ਸੈਕਸ਼ਨ ਵਿਚ ਇਕ ਵਰਗ ਇੰਚ ਅਤੇ 33.8 ਫੁੱਟ ਉੱਚਾ ਪਾਣੀ ਦੇ ਕਾਲਮ ਦੇ ਬਰਾਬਰ ਹੈ: ਸੱਠ- ਹਵਾ ਦਾ ਮੀਲ ਉੱਚਾ ਕਾਲਮ ਅਤੇ ਪਾਣੀ ਦਾ 33.8 ਫੁੱਟ ਉੱਚਾ ਕਾਲਮ ਦੋਵਾਂ ਦਾ ਭਾਰ 14.7 ਪੌਂਡ ਹੈ. ਬੇਸ਼ਕ ਹਵਾ ਤੁਸੀਂ ਜਿੰਨੀ ਉੱਚੀ ਜਾਂਦੇ ਹੋ ਪਤਲੀ ਅਤੇ ਹਲਕੀ ਹੋ ਜਾਂਦੀ ਹੈ ਅਤੇ ਧਰਤੀ ਦੀ ਵਕਰ ਦੇ ਕਾਰਨ ਕਾਲਮ ਬਹੁਤ ਥੋੜ੍ਹਾ ਜਿਹਾ ਟੇਪਰ ਜਾਂਦਾ ਹੈ - ਪਰ ਇਸ ਨਾਲ ਕੋਈ ਫਰਕ ਨਹੀਂ ਪੈਂਦਾ - ਇਸਦਾ ਭਾਰ ਅਜੇ ਵੀ ਪਾਣੀ ਦੇ .8 33.. ਫੁੱਟ ਉੱਚੇ ਕਾਲਮ ਦੇ ਸਮਾਨ ਹੈ.

(ਦਰਅਸਲ ਟੇਪਰ ਨਜ਼ਰਅੰਦਾਜ਼ ਹੁੰਦਾ ਹੈ ਜਦੋਂ ਤੁਸੀਂ ਮੰਨਦੇ ਹੋ ਕਿ ਸਪੇਸ ਆਮ ਤੌਰ 'ਤੇ ਲਗਭਗ ਸੱਠ ਮੀਲ ਦੀ ਦੂਰੀ' ਤੇ ਸ਼ੁਰੂ ਹੋਣ ਲਈ ਸਹਿਮਤ ਹੋ ਜਾਂਦਾ ਹੈ, ਅਤੇ ਧਰਤੀ ਦਾ ਘੇਰਾ ਤਕਰੀਬਨ ਚਾਰ ਹਜ਼ਾਰ ਮੀਲ ਹੈ. ਇਸੇ ਤਰ੍ਹਾਂ ਸੱਠ ਮੀਲ ਦੀ ਉਚਾਈ 'ਤੇ ਗੰਭੀਰਤਾ' ਚ ਕਮੀ ਵੀ ਘੱਟ ਹੈ.)

ਇਸ ਨੂੰ ਇਕ ਹੋਰ putੰਗ ਨਾਲ ਦੱਸਣ ਲਈ, ਅਤੇ ਆਪਣੇ 'ਫਟਣ' ਵਾਲੇ ਪ੍ਰਸ਼ਨ ਦਾ ਉੱਤਰ ਦੇਣ ਲਈ, ਇਹ ਸੱਚ ਹੈ ਕਿ ਜੇ ਤੁਸੀਂ ਸਿਲੰਡਰ ਨੂੰ ਹਵਾ ਨਾਲ ਭਰੇ ਹੋਏ ਸੱਤ ਫੁੱਟ ਹੇਠਾਂ ਡੁੱਬ ਸਕਦੇ ਹੋ ਅਤੇ ਫਿਰ ਧਰਤੀ ਦੇ ਸਾਰੇ ਵਾਤਾਵਰਣ ਨੂੰ ਜਾਦੂਈ removeੰਗ ਨਾਲ ਹਟਾ ਸਕਦੇ ਹੋ (ਅਸੀਂ ਹੁਣ ਮੰਨ ਲਵਾਂਗੇ ਕਿ ਪੂਲ ਚਾਹੁੰਦਾ ਹੈ) ਨਤੀਜੇ ਵਜੋਂ ਉਬਾਲ ਕੇ ਨਹੀਂ ਜਾਣਾ ਚਾਹੀਦਾ) ਤਾਂ ਸਿਲੰਡਰ ਦੇ ਅੰਦਰ ਦਾ ਦਬਾਅ ਸੱਚਮੁੱਚ ਬਾਹਰਲੇ ਪਾਣੀ ਨਾਲੋਂ 14.7 - 3 = 11.7 ਪੀ ਐਸ ਕੇ ਵੱਧ ਜਾਵੇਗਾ, ਇਸ ਲਈ ਕੋਈ ਵੀ ਲੀਕ ਤਦ ਚੀਰ / ਮੋਰੀ ਦੁਆਰਾ ਸਿਲੰਡਰ 'ਚੋਂ ਬਾਹਰ ਨਿਕਲਣ ਦੀ ਬਜਾਏ ਬਾਹਰ ਆਉਣ ਨਾਲ ਪਤਾ ਚੱਲੇਗਾ. ਪਾਣੀ ਦੀ ਲੀਕ
I reconize that not all of you are fluent in Punjabi so let me provide a precis of his remarks:
Wow, Ed, just wow. Once again you have demonstrated your unerring ability to do things. You have proven it to my satisfaction. Congratulations.
There is other stuff in there about pressure and other stuff that really does not move the peanut ahead.
thank you all for your interest and kind attention.

There was a funny thing in WKRP in Cincinnatti. They did a promotion for Thanksgiving where they dropped Turkeys out of a helicopter. One of the characters came into the newsroom with the plaintive cry "I didn't know turkey's couldn't fly". Always got me.

I didn't apprehend how well camouflaged crawdads are. I suspect there re hundreds of them there though.
