so if you have a pipe with water pressure and it cracks does the water leak out or the air leak in. ffs have lost all our senses. it aint rocket science.

let me give you another example. oil is lighter than water. when there is a pipeline with oil in the water and the pipe cracks, does the oil leak out or the water leak in. there are some mischievous children here who just dont understand nofink.

Your problem is, you are assuming that the pipe is filled with water 100% full at all times and under pressure, but if a lot of air builds up inside the pipe, then there isn't 100% water in the pipe, and then there is a crack in the pipe or a joint problem, as the air escapes into the sea, it is replaced by sea water as there would be also reduced pressure in the pipe as air escapes.

kikopoullos you have no idea. let me educate you. in fluid mechanics both air and water are fluids and obey the same physics laws. 20bar of air pressure is the same as 20 bar of water pressure. if there should any leaking in the pipe of any kind, it will act like a bleeder. first the air will escape and then the water. there is no way sea water can leak into the pipe so long as the pressure is higher inside. especiallywhen the water level in the pipe is higher than the sea level.

you are hopeless in politics as well as fluid mechanics. dont give up the day job or perhaps join the old fool at selling pots and pans, now there's a good old man.

I'm not talking about H2O as the chemical formula of water!

You are once again assuming that the water pipe is full 100% with water. How do you know that it is and it does not have large pockets of air in the pipes, and further more, how do you explain salt in the pipe water? Don't give me this crap about cleaning out the salt water from the time the pipes were being laid, because ALL the pipes would have been joined on the ship before being lowered to the sea to be anchored to the sea bottom. Even if there were some salt water in the pipes, surely it would have been flushed out right away and not still have salt water in the pipe.

[Nikitas]

The contractors who made money out of this, the British anchor makers, the German connector dude, I wonder what they have to say about their technology seeing the results. You dont hear much from them now. Low profile is their wise decisions.

[repulsewarrior]

...i wonder how much they are owed.

...in any case, if there are repairs to be made, they will be done after the winter storms.

You are not following up ANYTHING.
I told you I estimated the pressure needed to move it 80 Km to be 20 bar. (the head loss for this distance is 200m=20 bar).
This is the minimum required. How much they are using i DONT KNOW. But let's suppose they push it at 30 bar. The pressure outside the pipe at a depth of 280 meters is 28 bar. Notice the small difference with the 30 bar. If there would be a small leak then you are right water would flow out from the pipe into the sea. If there is a crack though, then while the pressure inside the pipe would be the same before the crack, we have a sudden loss of pressure after the crack. If the loss of pressure is such that after the crack drops below 28 bar then the crack will be flushing fresh water out from it's left half and draw sea water inside from it's right half.The bigger the crack the higher the problem.

You would expect everyone to be boosting their sales if this were a success. Not only them, but hundreds of countries and private contractors would line up in queue in Turkey to buy their patents and drawings and secrets.

[Pyrpolizer]

if there are any leaks the water will escape out of the pipe not in as the water pressure inside the pipe is higher than outside. first the assholes said it could not be done it was pipe dream and propaganda. now they are running around like a headless chickens commenting on things they know fuck all about.

At 280m depth? I don't think so.
But even if it were so, leaks here, leaks there =serious crack somewhere= loss of pressure and sea water coming in.

ehem ehem, how much work have you done working with pipes and water pressure. 280 meters is under 500 pounds per square inc. the pressure washers that you use to wash a car uses 130 bar compared to 28 bar at 280 meters. you really have no clue on what you are talking about.

now here is a thing, the water pressure inside the pipe is higher than the water pressure outside. gavole ise delya vosgos.

Just drill a small hole on the hose. I am sure you will see a lot of water flashing out from the hole, like you said, and like it is expected.
However check you nozzle too. Is it delivering water or water +air now? If it's the latter how the hell is air coming in?

[Pyrpolizer]

Now about the cracks. How the hell can such fine joints and flanges and stuff from Germany crack?
The reason like I said many times are the air pockets.There are no known devices to release air from pipes under the sea at depth of 280 m.
Probably the Turks designed something to do the job. However either all of those devices or some of them failed. Air started to accumulate.
This air pockets make the pipe burb and shake all the time. They often acts as detonators. Check your garden hose and see what happens when air accumulates in. I believe the pipes have already cracked on the upper side.

[Lordo]

who said anything about cracks. there is no cracks and the water is flowing.
