It would increase proportional to depth. All of this is figured out in engineering calculations long before the Bell is built and operated. Therefore there are no pressure gauges ( though there might be for air-recycling) inside the bell, which usually is cylindrically shaped. The ones I was one many years ago at Coney Island had no instruments per se- but had a vertical stack of three push-buttons for the up-down and elevate to dock functions, a switch controlling the air-scrubber, a fan of sorts, and a lever somewhat similar to a railroad brake valve or hand-brake lever- this was the ( Blow Negative) which released a powerful hydraulic spring- and sprang the bell to the surface. The operator would assure everybody was holding onto the safety handrail before shouting (Blow Negative) and flipping the lever- Buzz-Zoom-Pump! on the surface in little over a second. past joys now gone at Coney Island.

Why do people that want to go deep underwater need a submarine or dive bell?
The pressure of the water that deep would crush a person.
Does water boil at 220 degrees?
Water does boil at 212º Fahrenheit (100º Celsius) at the PRESSURE AT SEA LEVEL! The lower the pressure (higher altitude) the lower the boiling point of water. Or, if the pressure is manipulated, you can boil water at room temperature in a vacuum (lower pressure) using a bell jar and vacuum pump. As most cooks know, if water has a salt (say table salt) dissolved in it, it will slightly lower the boiling point of water at the same pressure/temperature conditions.
Cite an experiment to show that sound needs a material medium for its propagation?
Obtain a bell jar with a valve at the top, place the bell jar on a smooth flat surface. connect the valve to a vacuum pump through a rigid hose. Place a manual wind up spring alarm clock under the bell jar. Seal the bottom lip of the bell jar with petroleum jelly and ensure there are no gaps between the bell jar and the surface. Note the ticking of the clock. Start the vacuum pump and observe when the internal pressure begins to drop. Stop the vacuum pump and close the valve. Listen to the clocks ticking. Re start the vacuum pump and note the pressure drop, close the valve and listen to the ticking clock. As the pressure decreases the sounds of the clock will get fainter and fainter because there is less of the material medium (Air) to transfer the sound.
How was the speed of sound in water calculated 100 years ago?
A hundred years ago twp people on lake Geneva in Switzerland measured the speed of sound in water. One made a signal and started ringing a bell under the water.The other one started a stopwatch and then held his head under the water until he heard the bell.
What would happen to a bell in a glass jar if the air was removed?
If *all* of the air was removed, the bell would vibrate if it was rung, but there would be no air to carry the vibrations to the jar walls, so there would be no sound. If only part of the air was removed, the sound would be poorly carried and would not have the same amplitude (volume). (At around 1/100,000th of an atmosphere, low frequency sounds like a bell will no longer be carried because the molecules are farther apart than the wavelength. This is considered a near vacuum.)
What is a diving bell?
It is a device that looks like a bell and helps you dive into very deep places. the bell hosts the people in it sheilding them from the pressure.
Why would the boiling point of water be high in a pressurised deep sea diving bell?
As pressure increases, so does the temperature required to boil. See: http://www.engineeringtoolbox.com/boiling-point-water-d_926.html
When was Diving bell spider created?
Diving bell spider was created in 1758.
A scientific name for the water spider?
If you are referring to the diving bell spider, it is Argyroneta Aquatica.
Why does a diving spider surround itself with a bubble in the water?
Diving spiders make a sort of "diving bell" underwater. They live in there, so they need to fill it with air so they will have something to breathe. The spines on their body can trap air, so they rise to the top of the water, do a sort of somersault to throw themselves above the water surface and right back down into the water. When they come back under, they are covered in a bubble of air. They swim down to the diving bell where they shuck off the bubble of air. If there still is not enough air in their diving bell, then they may go back up again for another bubble.
What if the name of the inventor of the diving bell?
In 1616, the German inventor Kessler introduced his diving bell with glass ports
Why is a diving bell walls very thick?
To resist the water pressure, this is also true of the thickness of the viewing glass which sometimes is wire-reinforced like ports on, say armored cars, for maximum shock resistance.
Who are the diving bell inventors?
Eads
Do arthropods live in water?
Some do. Think crab, lobster, barnacle, horseshoe crab, water beetles and even diving bell spiders.
Where do you get the diving bell on Littlest Pet Shop Online?
you go to big catch and talk to the claws he will teach and give you a gem diving bell.
What contribution did eads and roebling's make to bridge construction?
Use of and invention of deep water caisons for divers, the diving bell
Why do people that want to go deep underwater need a submarine or dive bell?
The pressure of the water that deep would crush a person.
