I have been researching and trying to decide how many and what tanks I should get. Also if I should do my own filling with a shoebox etc
This was interesting and a bit sobering (and this is for a 3,300 psi tank, not a 4500 psi tank)
My local dive shop will fill a 80 cu ft Rated tank to 4500psi for $6. Seems pretty reasonable?
following was found on another web page:
"E = P0*V0*450So for a 230 bar 12L tank we have 230*12*450 Joules. 1242000 joules!
...
A joule is one watt for one second. so 1242000 joules is 3 kilowatts for just under 7 minutes.
That would boil 3.5 litres of water and so make coffee for everybody on the boat?
Still doesn't seem much does it? The trick is to release it in an instant.
...a unit of energy that was 4.184x1012 joules representing the energy released by 1000 tons of TNT.
That works out at about 1866000 joules per pound.
In metric units the tank contains the energy in 300 grams of TNT. A normal hand grenade has about 150 grams.
