Shamelessly copied from Nigel Hewitt who did the maths
Energy in a Scuba Tank Quote:
So for a 230 bar 12L tank we have 230*12*450 Joules. 1242000 joules!
<SNIP>
In metric units the tank contains the energy in 300 grams of TNT. A normal hand grenade has about 150 grams.
Hum. That works out at 650 grams for my 10L twins at 300 bar.
Just behind my head? Now I see why people worry about it.
