AH!! now we have edited the question!!
Cylinders are not normally coated with Kevlar unless they are made from the lightweight material CARBON FIBRE.
This Kevlar gives the carbon fibre some extra protection and a little more resistance to knocks and bangs.
The carbon/kevlar cylinders (they're not common) are much much lighter than a steel or Alloy cylinder so it saves weight for the diver on their back.
One drawback is that they are inherently buoyant.
Therefore they require an adjustment on weighting, and are not normally used in Technical diving as Stage Cylinders as they Bob up and get in the way.
The numbers on a scuba tank reveal 3 things. Serial no. of the tank. Type metal. and the current hydro date.
From a regulator attached to a scuba tank.
The empty weight of a 100 cubic foot steel SCUBA tank is approximately 33lbs.
Depends on the size of the tank.
Depends on the size of the tank.
I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.
the silly answer is you can store anything in a scuba tank that you can get in it!!. BUTthe serious answer is scuba tank were designed for compressed air and nothing else... using a scuba tank for natural gas is like driving around with a bomb in your car!!, the valves and collars of the bottles are not strong enough if there was a crash
No.
its the scuba tank on the swimming guys back.
You can use a scuba tank, but that is it.
Using a kevlar fabric as a base coat and coating it with an explosive-resistant spray may provide some level of protection against bullets, but it does not guarantee bulletproofing. The resistance to bullets depends on various factors such as the thickness and quality of the kevlar, the type and speed of the bullet, and the specific properties of the spray coating. It is essential to consult with experts and conduct thorough testing to determine the level of protection provided.
Kevlar is used to stop some bullets. Normally it will stop pistol rounds but other rounds , especially an anti tank round.
