I don't know why it only just now occurred to me to wonder how you measure the KG of something lighter (less dense) than air.
I know mass is not the same measurement as weight, but we still mostly use weight to measure mass, don't we?
Obviously this has already been solved for helium, but is it just measuring volume and converting? Or pressure level in a known volume? Or I guess if you pressurize it enough it'll be more dense than air.
What a fun problem!
- rawgabbit 2y agoI believe they use flow meters and convert that to kg. https://www.rheonik.com/company/h2-filling-stations https://www.rheonik.com/company/h2-filling-stations FYI from searching the internet and asking chatgpt, I came up with these rules of thumb regarding BTU equivalency: 10 gallons of California RFG gasoline is equivalent to 10 kg of hydrogen 12 CCF natural gas 9 gallons of low sulfur diesel 330 kWh of electricity The efficiency between internal combustion and BEV are of course dramatically different.
