1 KG of LPG =46,452 BTU's
Burn it for an hour and weight if before and after

Yah I saw that one and it didn't make any sense. "A" for effort though

I guess that's Scientific enough. Is there no standard calculation though?

really fine i'll try, whats the diameter of the orifice? 3/4?

Yes 3/4" pipe with a 0.023 mig tip inside.

7.92231 L/H
That does not seem reasonable tho, that would mean your using like 24 L an Hour, that would be of Gas not liquid

At WOT that could be true? The thing looks like its three tiger torches blowing full out all at once

Multiply the metric measure of liquid by the conversion ratio for propane. Since propane has a conversion ratio of 1:270, one unit of liquid propane yields 270 units of vaporous propane: 113.7 * 270 = 30,699.
Divide the uncompressed measure of propane by 1,000. This yields the number of cubic meters that the given amount of propane fills: 30,699 / 1000 = 30.7 rounded up, so your propane fills 30.7 cubic meters.
Convert from meters back into feet: 1 meter = 3.28 feet, but you're dealing with cubic feet. So, multiply your metric volume measure by 3.28^3: 30.7 * 3.28 * 3.28 * 3.28 = 1,083.32. Hence, 30 gallons of propane fills 1,083.32 cubic feet.

Still doesn't make sense to me. Maybe I'm missing something. A tiger torch has a rating of 500 000 BTUs. BBQs can be 50 000 easily. This thing does 10 times or more what a BBQ puts out. Thanks for the help by the way.

Just do it the first way lol
Otherwise you have determine the gas flow rate, Then covert that flow rate into a Liquid flow rate, then convert that in to KG per hour, then convert that into BTU's lol
ITs to complicated for me because the density of the gas changes as its compressed to 10 psi, That 1/270 assumes the gas is not compressed, what is the ratio when its compressed?

I'll just stick to my "one check mark on the side of the frame per half hour of use" system lol.

I can't tell what it is... What does it do?

It's just a gauge to tell level so you could figure out consumption.

Gotcha. Thanks!

The engineers that design the burners no doubt have a great calculation but they probably still test the designs just the way Wildman said. I'd do the weight burned per hour test.
