What does 5 ATM mean on a wrist watch?
"ATM" stands for ATMospheres and the number before it, refers to the number of atmospheres of pressure the watch will withstand before leaking. At sea level we are all subjected to one atmosphere of pressure, because we have one atmosphere of air above us pressing down. For every 33 feet (10 metres) underwater you go, the pressure increases by 1 atmosphere. Therefore, at 33 feet underwater the pressure is 2 atmospheres (2 ATM), at 66 feet underwater the pressure is 3 atmospheres (3 ATM), etc. So 5 ATM is equivalent to 132 feet (40 metres) underwater. In conclusion, the ATM rating of a watch is the number of atmospheres of pressure the watch will withstand before breaking/leaking. To convert ATM 's into the depth rating in metres just subtract 1 and multiply by 10. eg: 5 ATM = (5 - 1)*10 = 40 metres.
Why do diver wear diving suit?
for protection, as astronauts need to wear space suits to do space walks. Humans are fragile beings. Our skeletons and bone structure can only work in a narrow range of pressure around the atmospheric pressure [~1x105 Pa at sea level] -- we have adapted to earth's atmosphere. In deep seas, the human body will encounter a pressure [Pa], in addition to atmospheric pressure, equals to rho*g*h, where rho = water density [~ 1000 kg/m3]; g = 9.8 [m/s2]; and h is the water depth [m].
What is the pressure at 26000 feet below sea level?
I'm going to assume you mean underwater.The weight of a column of air from sea level to outer space is about the same as the weight of a column of water the same size 32 feet high. This is called "one atmosphere" of pressure. So, to find out the pressure at any depth, we just divide the depth by 32 feet to get the pressure in atmospheres. At 26000 feet, this amounts to 812.5 atmospheres... plus the one from the atmosphere itself, of course. This amounts to about 12000 pounds per square inch.
Can a diver go seven miles down to the bottom of the ocean?
they can go 1000 meters down !!! . but they have to have a tree near them Additional: There have been navy tests in cambers which divers have been under pressure to simulate dives to 2000 feet. Since most of the body in made up of uncompressable water in theory a diver could go to unlimited depth as long as the air he is breathing is reduce in oxygen and nitrogen to keep him from convulsing. And at a high enough pressure so his lungs would be equalized.. Question is how long would it take to come back up from deep deep "dive" with all the decompression needed. Tim
What would happen to the pressure if you cooled down the container?
The pressure inside the container would decrease.
What is the pressure of 5 meter depth under water?
The pressure at a depth of 5 meters under water is approximately 0.5 atmospheres, which is equivalent to 49 kilopascals. This pressure is caused by the weight of the water above pushing down on the water at that depth.
What is the pressure of ocean water at sea level?
Right at the surface of the ocean, the pressure is just the same as the air pressure at sea level; that is, one "atmosphere", or about 14.7 PSI (Pounds per Square Inch). But water pressure increases with increasing depth: For each foot of depth, the water pressure increases by 0.445 PSI. SCUBA divers, who need to be very aware their depth because of this pressure effect, often use this rule: Every 33 feet of depth, water pressure increases by one "atmosphere" (14.7 PSI). So, for example, at 66 feet the pressure on a diver is three atmospheres: There's one atmosphere of pressure from the air, and two atmospheres from the water.
What is the water pressure for 400 meters?
The water pressure at a depth of 400 meters is approximately 40 atmospheres or around 588 pounds per square inch (psi). This is due to the weight of the water above pressing down on the water at that depth.
How much pressure is there when you go ten meters under water?
The pressure at a depth of 10 meters underwater is about 2 atmospheres, which is equivalent to around 1 atmosphere of pressure at the surface plus an additional atmosphere for every 10 meters of depth. This increased pressure is due to the weight of the water above pushing down on you.
Why do divers watches say they are pressurized to three atmospheres?
This basically means that when the diver is underneath the water, the pressure down there is 3 times the pressure at normal land level. This means that the watch won't crack or break at three atmospheres worth of pressure.
What is water pressure depth at 50 m?
The water pressure at a depth of 50 meters is approximately 5 atmospheres or 73 psi (pounds per square inch). This means that the pressure increases by 1 atmosphere (14.7 psi) for every 10 meters of water depth due to the weight of the water above pressing down.
What is the water pressure at 2000 ft?
At a depth of 2000 feet below the surface of the water, the water pressure would be approximately 868.6 pounds per square inch (psi). This pressure increases by about 0.433 psi for every foot of depth due to the weight of the water above pushing down.
Does pressure depend on volume or depth?
Pressure depends on depth, not volume. Pressure increases with increasing depth due to the weight of the overlying fluid pressing down. Volume can affect pressure indirectly by changing the depth of the fluid column.
What is the relationship between water depth and pressure?
Pressure and depth are related in that pressure is proportional to depth. The equation to find pressure at a certain depth is p=dgh, where p is the pressure, d is the density, g is the acceleration of gravity and h is the depth.
Water pressure at depth of 150 meters?
Pressure in a liquid is given by: p = hdg where p is pressure at a point in the liquid h is the height of the liquid above the point d is the density pf the liquid g is the acceleration of free-fall So, water pressure = 150(1000)(10) = 1.5 x 106 Pa
True or false pressure increases as depth increases?
Yes, pressure does increase as your depth increases in the water
How is fluid pressure related to fluid depth?
Fluid pressure is directly related to fluid depth, as pressure increases with depth due to the weight of the fluid above pushing down. This relationship is described by the hydrostatic pressure formula, which states that pressure at a certain depth is proportional to the density of the fluid, the acceleration due to gravity, and the depth of the fluid.
