Miscellaneous Thermodynamic Related Information
One ton of cooling = 12000 Btu/hour
1 Btu * 1056 = 1 Joule
1 Joule = 1 Watt*sec
our shielding houses have 4 tons of cooling
4*12000*1056/60/60=14080 Watts
14kW of cooling per shielding house

Limit for flammable gas is 0.6 kg of H2 = 1.32 lb = 253 ft**3 ( @ 192 ft**3 / lb )
0.6kg of hydrogen = 50 SCF of ethane
Assuming 285 cubic feet per bottle and 62%/38% by volume.
This implies 285 * .38 = 109 cubic feet of ethane per bottle of premix.
