Standard emergency blow air tanks hold 3000psi air in them. However, they aren't normally used; during normal surfacing operations, a boat comes to periscope depth, raises its snorkel mast, then forces the water out using a Low Pressure Blower, which is essentially just a large hi-capacity fan. Sea pressure isn't that much above 100', so it takes a lot less pressure to force the water out with the LPB.
What else can I help you with?
What is sonar technology used for?
It is used for detecting submarines under water.
Why does submarines have to go under water?
Submarines are built with a special design that allows them to be faster underwater. Submarines can be used during a war as a way to sneak up to enemy lines in the water, but still stay hidden.
Which instrument is used in submarines to observe the surface of water?
A Periscope or Radar
What is the mechanism inside the motor which you used to pump water?
Water pumpWater pump
Which Instrument is used by submarines underwater to get a view above the surface of water?
periscope
How were periscopes used and how are they used now?
They were used in the first world war in submarines. The are used now also for submarines and also war tanks. The outer coating of the periscope for the submarines were firm and waterproof for protection from the water pressure. As for the war tank the periscope is able to turn 360 degrees.
Why is A submarine only used under water?
Because Submarines don't fly very well.
Who used the submarines?
During WW2, all the major countries involved used submarines.
What is a device used to move water out?
It is the water pump.
What is the device used to pump out excess water in freshwater organisms?
Water gun; Hydro pump.
How were sonar systems used in World War 2?
They were used by submarines to navigate when not in open waters, They were also used by submarines and anti-submarine ships to locate enemy submarines.
How do you calculate shared well monthly cost?
To determine the cost of electricity used by the well pump of a shared well you could: 1) run the pump's electrical wiring through a electrical meter. Electrical meters of sufficient wattage are available from many hardware stores. This method is fairly exact in finding out how much electricity the pump uses. Finding out how much of that electricity was used to pump your water vs their water can be determined by installation of water meters.
