You should use a number sufficient to provide for all oxygen needs expected. 42 is a good number.

The submersible found the Titanic and was used for many research projects. -74
To date (end of 2017) there has been208 climbers who have climbed Mount Everest without using oxygen cylinders (tanks) and 8,098 who have used oxygen cylinders.

How big are the two tanks, and how many guppies do you have
The cost of a submersible will vary by a huge amount, depending on specification.Anything from a few thousand dollars to many millions.
You need 1 oxygen atom for every 2 hydrogen atoms. If you're getting your pure gases in tanks of equal pressure you will thus need twice as many H tanks as O tanks. But because Oxygen Atoms weight alot more it will be a greater mass of O. if you have to much hydrogen you would make an acid
None.Apollo 1: had a fire but didn't explode.Apollo 13: Only the oxygen tanks exploded.
Submersible pumps can be applied to many distinct applications, from pumping large solids or grinding solids to smaller sizes, to transferring waste water at large flow rates or high pressures, to simply pumping up water off the floor or the bottom of a tank; depending upon submersible pump design. Some of the more common submersible pumps designed for specific applications include water submersible pumps, sewage submersible pumps, 12 volt submersible pumps, sand submersible pumps, irrigation submersible pumps, and solar submersible pumps. Solar submersible pumps, while not specific to an application, are best used for slow and steady water transference into a holding tank, but may also be used for direct pressurization applications.... that's my answer... shreya :)
600 tanks
what happened was that a coil got damaged and caused an explosion in one of the many oxygen tanks. this happened in April 13, 1970
There are several places to purchase a submersible water pump. Sears is a national retailer that sells the submersible water pump. There are also places online to purchase a submersible water pump such as Amazon, Water Pumps Direct, or Way Fair.
