Pressure tunnels are tunnels used to divert water from a reservoir, usually to a hydroeletric power house. They take their name due to the fact that, instead of most commons tunnels in wich the main load is geostatic (pointing inwards the tunnel), pressure tunnels are submited to high water pressures pointing outwards the tunnel.

Why is a water hose pulled into the ground when flowing?
to create a tunnel.
What does water pressure mean?
Water pressure refers to the pressure of water in a system. In a home it will be 30-50 psi typically and this is governed by the municipal pressure or by a well tank.
House water pressure?
House water pressure should be around 50-60 psi.
Will adding another water heater boost the water pressure in the house in addition to giving more hot water?
No and yes. No, you won't get more water pressure. To do that you'll need to find out why the water pressure is low. Perhaps flow restriction, perhaps a poorly adjusted water pressure regulator, perhaps low pressure from the well/city water. But an additional water heater will certainly give you more hot water. It would be like putting in a LARGER water heater. In most cities the water pressure required is about 20 PSI. Small city's do not add pressure pumps to their system but use a gravity supply. That is why most places there is a pressure problem either build their water tanks taller or erect them on a hill.
How do you improve water pressure in a house?
you can improve water pressure by installing a booster pump or if on a well then turn up your set pressure. If you had good pressure before and now are having poor pressure then it could be many reasons.
When was Päijänne Water Tunnel created?
Päijänne Water Tunnel was created in 1982.
When was Bolmen Water Tunnel created?
Bolmen Water Tunnel was created in 1987.
Why do your ears pop when you are in tunnel?
the pressure of the air
Was the Holland tunnel the first under water tunnel?
no
How do you build a tunnel in water?
There are several ways to build tunnels underwater.One way is to build sections of tubes in advance, float them into position using tugboats, sink them, have divers go down and seal the sections together, and then pump the water out.A more traditional way is to dig a tunnel far enough below the sea bottom that the rock over them keeps out the water. It's kind of like digging a mine,If the rock or soil isn't able to keep out all the water while the tunnel is being dug, sometimes it's possible to pump compressed air into the tunnel, so the pressure inside the tunnel is greater than the water pressure outside, and have workers seal the inside of the tunnel with a concrete or steel lining.Source(s):The wikipedia entry at http://en.wikipedia.org/wiki/Tunnel doesn't address underwater tunnelling much, but the entry at http://en.wikipedia.org/wiki/Tunnelling_… has some relevant information about how tunnels are kept from collapsing until they can be reinforced
What is the surgical enlargement of the carpal tunnel or cutting the carpal ligament to releive nerve pressure is called?
Carpal tunnel release
How does a carpel tunnel brace work?
A carpal tunnel brace helps by support and straightening the wrist to avoid pressure on the nerve.
Is the tyne tunnel built under water?
The Tyne River Tunnel is indeed built partly under water. The lowest spot in the tunnel is 85 feet below the high water mark of the river.
What is headrace tunnel?
A tunnel between De-silting basin or Fore-bay to Surge Shaft is called Head Race tunnel which may have pressure flow or gravity flow.
What towns does the channel tunnel go under?
The Channel is a body of water so the tunnel does not go under towns, but water.
Why forebay is used in hydroelectri power plant?
Head race tunnel are Non pressurized tunnels and Penstock is the tunnel bearing pressure. As there is the breakdown in the Power and the water is stopped entering through the turbines, the pressurized flow of water in the penstock creates hammer effect and goes back to the HRT. So, keeping Fore bay in between HRT and Penstock helps reducing pressurized water to create Water Hammers. Hence, to reduce the back water pressure effect, the Fore bay is used in the Hydro power Plant.
What is carpal tunnel release?
A carpal tunnel release is a surgical procedure performed to relieve pressure on the nerve located inside the carpal tunnel, an area in the wrist that supplies nerve function to the fingers.
